考虑以下 TikZ 代码。
\begin{tikzpicture}
\node[circle,fill=red] (1) at (4,7.5) {};
\node[circle,fill=green ] (2) at (8,8) {};
\node[circle,fill=blue] (4) at (5,7) {};
\node[circle,fill=violet] (3) at (8,5) {};
\node[circle,fill=orange] (5) at (9,4.5) {};
\node[circle,fill=red] (11) at (2,4) {};
\node[circle,fill=green ] (22) at (4,5) {};
\node[circle,fill=blue] (44) at (5,4) {};
\node[circle,fill=violet] (33) at (1,8) {};
\node[circle,fill=orange] (55) at (3,6.5) {};
\end{tikzpicture}
产生以下结果
我想画两个三角形如下
我们怎样才能画出它们?
答案1
如果我编译这个:
\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node[circle,fill=red] (1) at (4,7.5) {};
\node[circle,fill=green ] (2) at (8,8) {};
\node[circle,fill=blue] (4) at (5,7) {};
\node[circle,fill=violet] (3) at (8,5) {};
\node[circle,fill=orange] (5) at (9,4.5) {};
\draw[thick,color=red] (10,3)--(8,9)--(2.5,8)--(10,3);
\node[circle,fill=red] (11) at (2,4) {};
\node[circle,fill=green ] (22) at (4,5) {};
\node[circle,fill=blue] (44) at (5,4) {};
\node[circle,fill=violet] (33) at (1,8) {};
\node[circle,fill=orange] (55) at (3,6.5) {};
\draw[thick,color=red] (-1,10)--(9.5,3)--(2,3)--(-1,10);
\end{tikzpicture}
\end{document}
我得到的是:
