当我使用新版本的 tkz-euclide 时如何获得结果？

Question

这是我的代码

    \documentclass[border=2mm]{standalone}
\usepackage{tkz-euclide} % loads TikZ
\begin{document}
\begin{tikzpicture}
    \pgfmathsetmacro{\a}{2}
    \tkzDefPoint(0,0){O}
    \tkzDefPoint(-\a,0){A}
    \tkzDefPoint(\a,0){B}
    %\tkzDefCircle[through](O,C)
    \tkzDrawCircle(O,A)
    \tkzGetLength{rO}
\tkzDefPointOnCircle[angle=130,center=O,radius=\rO pt]
\tkzGetPoint{C}
\tkzDefPointOnCircle[angle=80,center=O,radius=\rO pt]
\tkzGetPoint{D}
\tkzDefPointOnCircle[angle=40,center=O,radius=\rO pt]
\tkzGetPoint{E}
    \tkzDefPointBy[symmetry=center C](A) \tkzGetPoint{M}
    \tkzDefPointBy[symmetry=center D](A) \tkzGetPoint{N}
    \tkzDefPointBy[symmetry=center E](A) \tkzGetPoint{P}
    \tkzDrawPoints(A,B,C,M,O,N,P,C,D,E)
    \tkzDrawSegments(A,M A,N A,P A,B)
    \tkzMarkSegments[mark=|](A,C M,C)
    \tkzMarkSegments[mark=||](A,D D,N)
    \tkzMarkSegments[mark=|||](A,E E,P)
    \foreach \p/\g in {A/180,B/0,M/90,O/-90,N/90,P/90,C/120,D/90,E/90}
    \path (\p)+(\g:3mm) node{$\p$};
\end{tikzpicture}
\end{document}

我怎样才能得到正确的结果？

Answer 1

使用最新版本 tkz-euclide 5.02c

\tkzGetLength{rO} is wrong

p.17 0.3. 与以前版本的变化\tkzCalcLength \tkzGetLength以厘米为单位给出结果；

备注：你定义的宏 \a, \rOA 没有用

`\tkzDefPointOnCircle[angle=130,center=O,radius=\rOA pt]` replaced by `\tkzDefPointOnCircle[R= center O angle 130 radius \rOA]`

    \tkzDefPoint(\a,0){B}
    %\tkzDefCircle[through](O,C)
    \tkzDrawCircle(O,A)
    %%%%%%%%%%%%%%%%%%%%%%
    %\tkzGetLength{rO}<--- wrong

    % \tkzCalcLength(O,A)\tkzGetLength{rOA}%<-- not useful
