\begin{problem}{1}
How do we know there are only six symmetries of the equilateral triangle? Prove that can be there no more.
\end{problem}

\label{fig:my_label}
\end{figure}
First, note the following six distinct symmetries of our equilateral triangle in Figure 1. From this we can observe that there are \textit{at least} 6 symmetries. Now, assume that we have a seventh symmetry that maps our original triangle ABC, to some new configuration of points A, B, and C. Note that there are only six possible permutations of three distinct objects (a result obtained from combinatorial counting). Hence, any seventh symmetry obtained must be by definition one of our original six symmetries.
\end{sol}

\begin{problem}{2}
What happens if you combine two of the six symmetries? Is the combination a new symmetry or equivalent to one of the original six? Prove your conjecture.
\end{problem}
\begin{sol}
Let $T_1, T_2$ be some distinct transformations of the plane. By definition, a symmetry is a 1-1 transformation (i.e. an isometry) that maps a geometric figure to itself. Since transformations are a special class of function $f: \mathbb{R}^2 \mapsto \mathbb{R}^2$, the composition of two symmetries of functions are also symmetries, by extension from the notion that compositions of isometries are also isometries.

我假设您实际上不希望图像从代码中提到的位置浮动。 根据这个假设，我提出了以下代码：
