我想概括这个图表并将其放在命令之前\begin{environment}，这样我就可以简单/轻松地在旋转正方形时更改数字。如果能在这方面得到帮助，我将不胜感激。

这是众多解决方案之一，其中包括\newcommand：
\documentclass[border=3.14mm]{standalone}
\usepackage{tikz}
\newcommand{\mysquare}[4]%
{%
\def\myradius{4cm}
\begin{tikzpicture}
\foreach \l [count=\i from 0] in {#1,#2,#3,#4}
{
\draw[fill=yellow!20] (45+90*\i:\myradius) rectangle (45+90*\i:0.8*\myradius);
\node at (45+\i*90:1.1*\myradius) {\l};
}
\draw[line width=1.5pt] (45:\myradius) rectangle (225:\myradius);
\end{tikzpicture}
}
\begin{document}
\mysquare{4}{1}{2}{3}
\hspace*{5mm}
\raisebox{2cm}
{
\begin{tikzpicture}
\draw[red, ultra thick, ->] (0,0) to [bend right=50] (2,0);
\node at (1,-.75) {$r_{90^\circ}=r$};
\end{tikzpicture}
}
\hspace*{5mm}
\mysquare{1}{2}{3}{4}
\end{document}
