![量角器的问题](https://linux22.com/image/324664/%E9%87%8F%E8%A7%92%E5%99%A8%E7%9A%84%E9%97%AE%E9%A2%98.png)
如何设置量角器来测量A,C,B
角度?
代码
\documentclass[12pt,a4paper]{article}
\usepackage{tikz,tkz-euclide}
\usetkzobj{all}
\begin{document}
\begin{tikzpicture}
\tkzDefPoints{0/0/A, 6/0/B, 3/3/C}
\tkzDrawPolygon[draw=red,very thick,fill=red,fill opacity=.4](A,B,C)
\tkzDrawPoints(A,B,C)
\tkzLabelPoints(A,B,C)
%\tkzDrawCircle[in](A,B,C)
\tkzDrawCircle[circum](A,B,C)
\tkzProtractor[with=half](C,B)
\end{tikzpicture}
\end{document}
它有什么问题?
答案1
像这样?我不明白你想测量哪个角度。
\documentclass[12pt,a4paper]{article}
\usepackage{tikz,tkz-euclide}
\usetkzobj{all}
\begin{document}
\begin{tikzpicture}
\tkzDefPoints{0/0/A, 6/0/B, 3/3/C}
\tkzDrawPolygon[draw=red,very thick,fill=red,fill opacity=.4](A,B,C)
\tkzDrawPoints(A,B,C)
\tkzLabelPoints(A,B,C)
%\tkzDrawCircle[in](A,B,C)
\tkzDrawCircle[circum](A,B,C)
\tkzProtractor[with=half](A,B)
\end{tikzpicture}
\end{document}
更新:
如果要测量直角,请在选项中添加return
(或rotate
) :proactor
\documentclass[12pt,a4paper]{article}
\usepackage{tikz,tkz-euclide}
\usetkzobj{all}
\begin{document}
\begin{tikzpicture}
\tkzDefPoints{0/0/A, 6/0/B, 3/3/C}
\tkzDrawPolygon[draw=red,very thick,fill=red,fill opacity=.4](A,B,C)
\tkzDrawPoints(A,B,C)
\tkzLabelPoints(A,B,C)
%\tkzDrawCircle[in](A,B,C)
\tkzDrawCircle[circum](A,B,C)
\tkzProtractor[with=half, return](C,B)
\end{tikzpicture}
\end{document}
