tkz-euclide 宏包中如何获取未知角的度数并用在另一个角的绘制中

我要成为Typst糕手/(ㄒoㄒ)/~~

先解决原始问题

注意

\tkzGetAngle(angleADG)

与

\tkzGetAngle{angleADG}

看文档的例子：

所以，你只要把\tkzGetAngle(angleADG)替换为\tkzGetAngle{angleADG}即可

\documentclass[border=5pt]{standalone}
\usepackage{tkz-euclide}

\begin{document}
    \begin{tikzpicture}
        
        % ===== 定义点 =====
        \tkzDefPoints{0/0/C, 4/0/E}
        \tkzDefTriangle[two angles=23 and 37](C,E)
        \tkzGetPoint{B}
        
        \tkzDefPointBy[rotation=center B angle -90](C)
        \tkzGetPoint{A}
        \tkzDefPointBy[rotation=center B angle 90](E)
        \tkzGetPoint{D}
        
        \tkzCalcLength(B,D)
        \tkzGetLength{BDlen} 
        \tkzDefPointWith[linear normed, K=\BDlen](B,A) 
        \tkzGetPoint{G}
        
        \tkzFindAngle(A,D,G)
        \tkzGetAngle{angleADG}%<-注意花括号
        \tkzDefPointBy[rotation=center B angle \angleADG](A)
        \tkzGetPoint{f}
        \tkzInterLL(B,f)(A,D)
        \tkzGetPoint{F}
        

        % ===== 绘制图形 =====
        \tkzDrawPolygon[thick](B,C,E)
        \tkzDrawSegments[thick](A,B D,B A,C D,E A,D D,G B,F G,F)
        
    \end{tikzpicture}
\end{document}

一个workaround：

如果只要用一次，那么也可以直接用\tkzAngleResult，这样可以不用再\tkzGetAngle多写一行...

\documentclass[border=5pt]{standalone}
\usepackage{tkz-euclide}
\begin{document}
    \begin{tikzpicture}[font=\small]
        % ===== 定义点 =====
        \tkzDefPoints{0/0/C, 4/0/E}
        \tkzDefTriangle[two angles=23 and 37](C,E)
        \tkzGetPoint{B}
        
        \tkzDefPointBy[rotation=center B angle -90](C)
        \tkzGetPoint{A}
        \tkzDefPointBy[rotation=center B angle 90](E)
        \tkzGetPoint{D}
        
        \tkzCalcLength(B,D)
        \tkzGetLength{BDlen} 
        \tkzDefPointWith[linear normed, K=\BDlen](B,A) 
        \tkzGetPoint{G}
        
        \tkzFindAngle(A,D,G)
        % \tkzGetAngle(angleADG)
        \tkzDefPointBy[rotation=center B angle \tkzAngleResult](A)
        \tkzGetPoint{f}
        \tkzInterLL(B,f)(A,D)
        \tkzGetPoint{F}
        

        % ===== 绘制图形 =====
        \tkzDrawPolygon[thick](B,C,E)
        \tkzDrawSegments[thick](A,B D,B A,C D,E A,D D,G B,F G,F)
    \end{tikzpicture}
\end{document}
