我正在尝试重新创建此图表。除了顶角的标签外,我可以得到大部分内容。
MWE 如下
\documentclass{article}
\usepackage{tikz}
\usepackage{tkz-euclide}
\usetkzobj{all}
\begin{document}
\begin{tikzpicture}[thick]
\coordinate (O) at (0,0);
\coordinate (A) at (4,0);
\coordinate (B) at (0,2);
\draw (O)--(A)--(B)--cycle;
\node (a) at (1.4,2.1) {$90^{\circ}-\theta$};
\node (b) at (0.1,1.8){};
\path (a) edge [->,bend left=45,looseness=0.8] (b);
\tkzLabelSegment[below=2pt](O,A){$b$}
\tkzLabelSegment[left=2pt](O,B){$a$}
\tkzLabelSegment[above right=2pt](A,B){$c$}
\tkzMarkRightAngle[size=0.3](A,O,B)
\tkzLabelAngle[pos = 1.0](O,A,B){$\theta$}
\end{tikzpicture}
\end{document}
