我找到了一种非常好的方法来编写高中的两列几何证明,但我似乎找不到这个包。它没有出现在 MikTeX 2.9 中,谷歌也没有显示任何信息。这是 Overleaf 上这个包的示例。
\usepackage{TwoColumnProof}
\title{Two-Column Proof Example}
\begin{document}
\includegraphics[width=.3\textwidth]{sampleproof}
\section*{Given:}
\begin{itemize}
\item Segment AD bisects segment $BC$.
\item Segment BC bisects segment $AD$.
\end{itemize}
\section*{Prove:}
\begin{itemize}
\item $\triangle ABM$ and $\triangle DCM$ are congruent.
\end{itemize}
\begin{TwoColumnProof}
\StatementReason{Segment $AD$ bisects segment $BC$.}
{Given.}
\StatementReason{Segments $AM$ and $MD$ are congruent. \label{label1}}
{When a segment is bisected, the two resulting segments are congruent.}
\StatementReason{Segment $BC$ bisects segment $AD$.}
{Given.}
\StatementReason{Segments $BM$ and $CM$ are congruent.}
{When a segment is bisected, the two resulting segments are congruent.}
\StatementReason{$\angle AMB$ and $\angle DMC$ are congruent.}
{Verticle angles are congruent.}
\StatementReason{$\triangle ABM$ and $\triangle DCM$ are congruent.}
{SAS postulate (2, 4, 5).}
\end{TwoColumnProof}
\end{document}
有人能帮忙吗?
