我已经使用包定义了一种新的定理样式amsthm
,并且我注意到\parindent
我在样式的定义中包含了带有注释的代码行,indentation amount
为头定理的标题而不是定理的正文,这是更理想的。我还注意到,如果我使用预定义的默认样式,它amsthm
会在定理的正文中添加缩进,而不是我想要的标题。为了明确我的愿望:我希望定理的标题带有不缩进和定理正文和缩进。我做错了什么,如何在新定理样式的定义中控制定理正文的缩进?查看了文档,amsthm package
我没有找到任何可以帮助我的东西。

Let $ABC$ right triangle with $\angle A=90^{\circ}$. Then for the sides of the triangle $AB, AC$ and $BC$ is true that:
\begin{equation}
(BC)^{2}=(AB)^2+(AC)^{2}
\end{equation}

答案1
您可以将changepage
包添加到您的序言中并使用该adjustwidth
环境。更改<indent param>
字段以满足您的需求。
\begin{thm}(Theorem of Pythagoras)
\begin{adjustwidth}{<indent param>}{}
Let $ABC$ right triangle with $\angle A=90^{\circ}$. Then for the sides of the triangle $AB, AC$ and $BC$ is true that:
\begin{equation}
(BC)^{2}=(AB)^2+(AC)^{2}
\end{equation}
\end{adjustwidth}
\end{thm}
编辑
您可以创建自定义环境:
\newenvironment{indented}[1]{
\begin{thm}[#1]\phantom\newline\vspace{-\baselineskip}\begin{adjustwidth}{<indent space>}{}}
{\end{adjustwidth}\end{thm}}
像这样使用它:
\begin{indented}{Pythagoras}
Let $ABC$ right triangle with $\angle A=90^{\circ}$. Then for the sides of the triangle $AB, AC$ and $BC$ is true that:
\begin{equation}
(BC)^{2}=(AB)^2+(AC)^{2}
\end{equation}
\end{indented}
针对您下方的评论的其他解决方案
\newenvironment{indented}[1]{
\setlength\parindent{<change it to set indent amount>}
\begin{thm}[#1]\phantom\newline\vspace{-\baselineskip}\begin{adjustwidth}{0cm}{}\hspace{\parindent}}
{\end{adjustwidth}\end{thm}}
