我需要做这张照片...
这是我的起始代码。我该如何绘制角度?以及虚线?谢谢!

这里提供了一个带有软件包的替代解决方案tkz-euclide
,只是为了完整性。

答案2
不幸的是你的 MWE 无法编译...所以我从中制作了自己的:
编辑:为了生成更紧凑的角度表示并展示对角度标签位置的可能控制angle eccentricity
,我稍微改变了原始答案(删除所有未使用的包,将两张图片移动到一行中):
\documentclass[a4paper,12pt]{article}
\usepackage{xcolor}
\usepackage{tikz}
\usetikzlibrary{angles,calc,intersections,quotes}
\usepackage[a4paper,top=1.3cm,bottom=1.3cm,left=1.5cm,right=1.5cm]{geometry}
\begin{document}
\begin{tikzpicture}[
> = stealth,
angle radius = 12mm,
my angle/.style = {draw, fill=#1,
angle eccentricity=1.2} % angle label position!
]
\draw[gray,step=1cm] (0,0) grid +(15cm,7cm);
\coordinate (A0) at ( 9,1);
\node (Ay) at ( 9,7) [above] {$y$};
\node (Ax) at (12,1) [right] {$x$};
\coordinate (A) at (12,7);
\path (A0) edge[thick,->] (Ax)
(A0) edge[thick,->] (Ay)
(A0) edge[ultra thick] (A)
pic [my angle=blue!30, "$\beta$"] {angle = Ax--A0--A}
pic [my angle=red!30, "$\gamma$"] {angle = A--A0--Ay};
\draw[dashed] (Ay.south) -| (Ax.west);
%
\coordinate (B0) at (4,4);
\node (By) at (4,6) [above] {$y$};
\coordinate (Bx1)at (2,4);
\node (Bx2)at (6,4) [right] {$x$};
\coordinate (B1) at (2,6);
\coordinate (B2) at (6,6);
\path (Bx1) edge[thick,->] (Bx2)
(B0) edge[thick,->] (By)
(B0) edge[ultra thick] (B1)
(B0) edge[ultra thick] (B2)
pic [my angle=red!30, "$\alpha$"] {angle = Bx2--B0--B2}
pic [my angle=blue!30, "$\beta$"] {angle = B2--B0--By}
pic [my angle=blue!30, "$\beta$"] {angle = By--B0--B1}
pic [my angle=red!30, "$\alpha$"] {angle = B1--B0--Bx1};
\end{tikzpicture}

我希望我没有遗漏对您来说至关重要的内容。您可以轻松添加枚举、迷你页面等。此外,要更改图片位置,您只需要适当更改/重新计算图片坐标即可。
如您所见,对于角度,我使用小图片pic
。为了使用它们,我添加了两个包:angles
和quotes
。
