\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.}
