\section{Random point definition} %<---------------------------------------------------------------------------> % points random %<---------------------------------------------------------------------------> At the moment there are four possibilities: \begin{enumerate} \item point in a rectangle; \item on a segment; \item on a straight line; \item on a circle. \end{enumerate} \subsection{Obtaining random points} This is the new version that replaces \tkzcname{tkzGetRandPointOn}. \begin{NewMacroBox}{tkzDefRandPointOn}{\oarg{local options}}% {The result is a point with a random position that can be named with the macro \tkzcname{tkzGetPoint}. It is possible to use \tkzname{tkzPointResult} if it is not necessary to retain the results.} \medskip \begin{tabular}{lll}% \toprule options & default & definition \\ \midrule \TOline{rectangle=pt1 and pt2} {}{[rectangle=A and B]} \TOline{segment= pt1--pt2} {}{[segment=A--B]} \TOline{line=pt1--pt2}{}{[line=A--B]} \TOline{circle =center pt1 radius dim}{}{[circle = center A radius 2]} \TOline{circle through=center pt1 through pt2}{}{[circle through= center A through B]} \TOline{disk through=center pt1 through pt2}{}{[disk through=center A through B]} \end{tabular} \end{NewMacroBox} \subsubsection{Random point in a rectangle} \begin{tkzexample}[latex=7cm,small] \begin{tikzpicture} \tkzDefPoints{0/0/A,5/3/C} \tkzDefRandPointOn[rectangle = A and C] \tkzGetPoint{E} \tkzDefRectangle(A,C)\tkzGetPoints{B}{D} \tkzDrawPolygon[red](A,...,D) \tkzDrawPoints(A,...,E) \tkzLabelPoints(A,...,E) \end{tikzpicture} \end{tkzexample} \subsubsection{Random point on a segment or a line} \begin{tkzexample}[latex=7cm,small] \begin{tikzpicture} \tkzDefPoints{0/0/A,5/2/C} \tkzDefRandPointOn[segment = A--C]\tkzGetPoint{B} \tkzDrawLine(A,C) \tkzDrawPoints(A,C) \tkzDrawPoint[red](B) \tkzLabelPoints(A,C) \tkzLabelPoints[red](B) \end{tikzpicture} \end{tkzexample} \subsubsection{Random point on a circle or a disk} \begin{tkzexample}[latex=7cm,small] \begin{tikzpicture} \tkzDefPoints{3/2/A,1/1/B} \tkzCalcLength(A,B) \tkzGetLength{rAB} \tkzDefRandPointOn[circle = center A radius \rAB] \tkzGetPoint{C} \tkzDefRandPointOn[circle through= center A through B] \tkzGetPoint{D} \tkzDefRandPointOn[disk through=center A through B] \tkzGetPoint{E} \tkzDrawCircle[R](A,\rAB) \tkzDrawPoints(A,B) \tkzLabelPoints(A,B) \tkzDrawPoints[red](C,D,E) \tkzLabelPoints[red](C,D,E) \end{tikzpicture} \end{tkzexample} \endinput
