 tkz-euclide is a package (latex) which allows you to draw
   two-dimensional geometric figures, in other words to create figures of Euclidean geometry. It uses a Cartesian coordinate system orthogonal provided by the tkz-base package as well as tools to define the unique coordinates of points and to manipulate them. The idea is to allow you to follow step by step a construction that would be done by hand as naturally as possible.

 \item Do not mix the syntax of \tkzNamePack{pgfmath} and \tkzNamePack{xfp}. I've often chosen \tkzNamePack{xfp} but if you prefer pgfmath then do your calculations before passing parameters.
 
-\item Use of \tkzcname{tkzClip} : In order to get accurate results, I avoided using normalized vectors. The advantage of normalization is to control the dimension of the manipulated objects, the disadvantage is that with TeX, this implies inaccuracies. These inaccuracies are often small, in the order of a thousandth, but they lead to disasters if the drawing is enlarged. Not normalizing implies that some points are far away from the working area and \tkzcname{tkzClip} allows you to reduce the size of the drawing.

 \item  An error occurs if you use the macro \tkzcname{tkzDrawAngle}
  with too small an angle. The error is produced by the \NameLib{decoration} library when you want to place a mark on an arc. Even if the mark is absent, the error is still present. It is possible to get around this difficulty with the option \tkzname{mkpos=.2} for example, which will place the mark before the arc. Another possibility is to use the macro \tkzcname{tkzFillAngle}.

-\section{Draw, Label The Circles}
-
-Among the following macros, one will allow you to draw a circle, which is not a real feat. To do this, you will need to know the center of the circle and either the radius of the circle or a point on the circumference. It seemed to me that the most frequent use was to draw a circle with a given centre passing through a given point. This will be the default method, otherwise you will have to use the \tkzname{R} option. 
 
+\section{Draw, Label the Circles}
 \begin{itemize}
  \item  I created a first macro  \tkzcname{tkzDrawCircle},
  
  \item then a macro that allows you to color a disc, but without drawing the circle. \tkzcname{tkzFillCircle},
  
- \item sometimes, it is necessary for a drawing to be contained in a disc is the role assigned to \tkzcname{tkzClipCircle},
+ \item sometimes, it is necessary for a drawing to be contained in a disc,this is the role assigned to \tkzcname{tkzClipCircle},
 
  
  \item  It finally remains to be able to give a label to designate a circle and if several possibilities are offered, we will see here \tkzcname{tkzLabelCircle}.

-To draw a normal straight line, just give a couple of points. You can  use the \tkzname{add} option to extend the line.( This option is due to \tkzimp{Mark Wibrow} ). 
-
-In the special case of lines defined in a triangle, the number of arguments is a list of three points (the vertices of the triangle). The second point is where the line will come from. The first and last points determine the target segment. The old method has therefore been slightly modified. So for \tkzcname{tkzDrawMedian}, instead of |(A,B)(C)| you have to write |(B,C,A)| where C is the point that will be linked to the middle of the segment |[A,B]|.

-The \tkzname{\tkznameofpack} is a set of convenient macros for drawing in a plane ( fundamental two-dimensional object) with a Cartesian coordinate system. It  handles the more classic situations in Euclidean Geometry. \tkzname{\tkznameofpack} is built on top of PGF and its associated front-end \TIKZ\ and is a (La)TeX-friendly drawing package. The aim is to provide a high-level user interface  to build graphics  relatively simply. It uses a Cartesian coordinate system orthogonal provided by the \tkzimp{tkz-base} package as well as tools to define the unique coordinates of points and to manipulate them. The idea is to allow you to follow step by step a construction that would be done by hand as naturally as possible.\\

It uses a Cartesian coordinate system orthogonal provided by the \tkzimp{tkz-base} package as well as tools to define the unique coordinates of points and to manipulate them. The idea is to allow you to follow step by step a construction that would be done by hand as naturally as possible.\\
 Now the package needs the version 3.0 of \TIKZ.  English is  not my native language so there  might be some errors.

-\item  Logically most macros accept TikZ options. So I removed the "duplicate" options when possible; thus the "label options" option is removed.
 
-\item Random points are now in \tkzimp{tkz-euclide} and the macro \tkzcname{tkzGetRandPointOn} is replaced by \tkzcname{tkzDefRandPointOn}. For homogeneity reasons, the points must be retrieved with \tkzcname{tkzGetPoint}.

-\subsubsection{\IoptName{tkzDefTriangleCenter}{in}}
- In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle's incenter.
- The center of the incircle, called the incenter, can be found as the intersection of the three internal angle bisectors. The center of an excircle is the intersection of the internal bisector of one angle (at vertex A, for example) and the external bisectors of the other two. The center of this excircle is called the excenter relative to the vertex A, or the excenter of A.[3] Because the internal bisector of an angle is perpendicular to its external bisector, it follows that the center of the incircle together with the three excircle centers form an orthocentric system.(\url{https://en.wikipedia.org/wiki/Incircle_and_excircles_of_a_triangle})
- 
- \medskip
- We get the centre of the inscribed circle of the triangle. The result is of course in \tkzname{tkzPointResult}. We can retrieve it with \tkzcname{tkzGetPoint}.

-\subsubsection{Utilisation de \IoptName{tkzDefTriangleCenter}{euler} }
-This macro allows to obtain the center of the circle of the nine points or euler's circle or Feuerbach's circle.
-The nine-point circle, also called Euler's circle or the Feuerbach circle, is the circle that passes through the perpendicular feet $H_A$, $H_B$, and $H_C$ dropped from the vertices of any reference triangle ABC on the sides opposite them. Euler showed in 1765 that it also passes through the midpoints $M_A$, $M_B$, $M_C$ of the sides of ABC. By Feuerbach's theorem, the nine-point circle also passes through the midpoints $E_A$, $E_B$, and $E_C$ of the segments that join the vertices and the orthocenter H. These points are commonly referred to as the Euler points. (\url{http://mathworld.wolfram.com/Nine-PointCircle.html})

+In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle's incenter.
+The center of the incircle, called the incenter, can be found as the intersection of the three internal angle bisectors. The center of an excircle is the intersection of the internal bisector of one angle (at vertex $A$, for example) and the external bisectors of the other two. The center of this excircle is called the excenter relative to the vertex $A$, or the excenter of $A$. Because the internal bisector of an angle is perpendicular to its external bisector, it follows that the center of the incircle together with the three excircle centers form an orthocentric system.(\url{https://en.wikipedia.org/wiki/Incircle_and_excircles_of_a_triangle})
+ 
+ \medskip
+ We get the centre of the inscribed circle of the triangle. The result is of course in \tkzname{tkzPointResult}. We can retrieve it with \tkzcname{tkzGetPoint}.

+An excircle or escribed circle of the triangle is a circle lying outside the triangle, tangent to one of its sides and tangent to the extensions of the other two. Every triangle has three distinct excircles, each tangent to one of the triangle's sides.
+(\url{https://en.wikipedia.org/wiki/Incircle_and_excircles_of_a_triangle})
+
+
+ We get the centre of an inscribed circle of the triangle. The result is of course in \tkzname{tkzPointResult}. We can retrieve it with \tkzcname{tkzGetPoint}.

+\subsubsection{Option \tkzname{euler}}
+This macro allows to obtain the center of the circle of the nine points or euler's circle or Feuerbach's circle.
+The nine-point circle, also called Euler's circle or the Feuerbach circle, is the circle that passes through the perpendicular feet $H_A$, $H_B$, and $H_C$ dropped from the vertices of any reference triangle $ABC$ on the sides opposite them. Euler showed in 1765 that it also passes through the midpoints $M_A$, $M_B$, $M_C$ of the sides of $ABC$. By Feuerbach's theorem, the nine-point circle also passes through the midpoints $E_A$, $E_B$, and $E_C$ of the segments that join the vertices and the orthocenter $H$. These points are commonly referred to as the Euler points. (\url{http://mathworld.wolfram.com/Nine-PointCircle.html})

 \subsection{\tkzcname{tkzDefPointWith}}
 There are several possibilities to create points that meet certain vector conditions.
-This can be done with \tkzcname{tkzDefPointWith}. The general principle is as follows, two points are passed as arguments, i.e. a vector. The different options allow to obtain a new point forming with the first point ( with some exceptions) a collinear vector or a vector orthogonal to the first vector. Then the length is either proportional to that of the first one, or proportional to the unit. Since this point is only used temporarily, it does not have to be named immediately. The result is in \tkzcname{tkzPointResult}. The macro \tkzNameMacro{tkzGetPoint} allows you to retrieve the point and name it differently.

  There are options to define the distance between the given point and the obtained point.
 In the general case this distance is the distance between the 2 points given as arguments if the option is of the "normed" type then the distance between the given point and the obtained point is 1 cm. Then the $K$ option allows to obtain multiples.

 It appeared that the simplest method was to reproduce the one used to obtain construction by hand. 
-To describe a construction, you must of course define the objects but also the actions that you perform. It seemed to me that a syntax close to the language of mathematicians and their students would be more easily understandable; moreover, it also seemed to me that this syntax should be close to that of LaTeX. 
-The objects of course are points, segments, lines, triangles, polygons and circles. As for actions, I considered five to be sufficient, namely: define, create, draw, mark and label.

 That said, I don't think mixing syntax is a good thing. 
 
-There is no need to compare TikZ and tkz-euclide.  The latter is not addressed to the same audience as Tikz. The first one allows you to do a lot of things, the second one only does geometry drawings. The first one can do everything the second one does, but the second one will more easily do what you want.

-\subsection{Conventions}
+\subsection{Notations and conventions}
+
+I deliberately chose to use the geometric French and personal  conventions  to describe the geometric objects represented. The objects defined and represented by \tkzname{\tkznameofpack} are points, lines and circles located in a plane. They are the primary objects of Euclidean geometry from which we will construct figures.
+
+According to \tkzimp{Euclidian} these figures will only illustrate pure ideas produced by our brain.
+Thus a point has no dimension and therefore no real existence. In the same way the line has no width and therefore no existence in the real world. The objects that we are going to consider are only representations of ideal mathematical objects. \tkzname{\tkznameofpack} will follow the steps of the ancient Greeks to obtain geometrical constructions using the ruler and the compass. 
+
+Here are the notations that will be used:
+
+
+\begin{itemize}
+\item The points are represented geometrically either by a small disc or by the intersection of two lines (two straight lines, a straight line and a circle or two circles). In this case, the point is represented by a cross. 
+

-For this documentation, I used the geometric French and personal  conventions for naming the points: 
+The existence of a point being established, we can give it a label which will be a capital letter (with some exceptions) of the Latin alphabet such as $A$, $B$ or $C$. For example:
 \begin{itemize}
 \item $O$ is a center for a circle, a rotation, etc.;
 \item $M$ defined a midpoint;
 \item $H$ defined the foot of an altitude;
 \item $P'$ is the image of $P$ by a transformation ;
-\item $a$ defined an angle (degree), $r$ the length of a radius, $d$ a length (or dimension);
-\item ($x_1$,$y_1$) coordinates of the point $A_1$, ($x_A$,$y_A$) coordinates of the point $A$;
-\item $[AB]$ a line segment, $(AB)$ a line.
 \end{itemize}
 
-\subsection{How to use the tkz-euclide package ?}
+It is important to note that the reference name of a point in the code may be different from the label to designate it in the text. So we can define a point A and give it as label $P$. In particular the style will be different, point A will be labeled $A$. 
+
+\begin{tkzexample}[latex=6cm, small]     
+  \begin{tikzpicture}       
+    \tkzDefPoints{0/0/A}       
+    \tkzDrawPoints(A)       
+    \tkzLabelPoint(A){$P$}     
+  \end{tikzpicture}    
+\end{tkzexample}
+
+Exceptions: some points such as the middle of the sides of a triangle share a characteristic, so it is normal that their names also share a common character. We will designate these points by $M_a$, $M_b$ and $M_c$ or $M_A$, $M_B$ and $M_C$.
+
+In the code, these points will be referred to as: M\_A, M\_B and M\_C.
+
+Another exception relates to intermediate construction points which will not be labelled. They will often be designated by a lowercase letter in the code.
+
+\item The line segments are designated by two points representing their ends in square brackets: $[AB]$. 
+
+\item The straight lines are in Euclidean geometry defined by two points so $A$ and $B$ define the straight line $(AB)$. We can also designate this stright line using the Greek alphabet and name it $(\delta)$ or $(\Delta)$. It is also possible to designate the straight line with lowercase letters such as $d$ and $d'$.
+
+\item The semi-straight line is designated as follows $[AB)$.
+
+
+\item Relation between the straight lines. Two perpendicular $(AB)$ and $(CD)$ lines will be written $(AB) \perp (CD)$ and if they are parallel we will write $(AB) \parallelslant (CD)$.
+
+\item The lengths of the sides of triangle ABC are $AB$, $AC$ and $BC$. The numbers are also designated by a lowercase letter so we will write: $AB=c$, $AC=b$ and $BC=a$. The letter $a$ is also used to represent an angle, and $r$ is frequently used to represent a radius, $d$ a diameter, $l$ a length, $d$ a distance.
+
+\item Polygons are designated afterwards by their vertices so $ABC$ is a triangle, $EFGH$ a quadrilateral.
+
+\item Angles are generally measured in degrees (ex $60^\circ$) and in an equilateral $ABC$ triangle we will write $\widehat{ABC}=\widehat{B}=60^\circ$.
+
+\item The arcs are designated by their extremities. For example if $A$ and $B$ are two points of the same circle then $\widearc{AB}$.
+
+
+\item Circles are noted either $\mathcal{C}$ if there is no possible confusion or $\mathcal{C}$ $(O~;~A)$ for a circle with center $O$ and passing through the point $A$ or $\mathcal{C}$ $(O~;~1)$ for a circle with center O and radius 1 cm.
+
+\item  Name of the particular lines of a triangle: I used the terms bisector, bisector out, mediator (sometimes called perpendicular bisectors), altitude, median and symmedian.
+
+\item ($x_1$,$y_1$) coordinates of the point $A_1$, ($x_A$,$y_A$) coordinates of the point $A$.
