只画一个,后面的你可以选择套用循环,或者复制粘贴
\documentclass{ctexart}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node [ circle, draw ] (a) {};
\node [ circle, draw, fill, xshift = 1cm ] (b) at (a) {};
\node [ circle, draw, fill, shift = {({sin(18)}, {cos(18)})} ] (c) at (b) {};
\node [ circle, draw, fill, shift = {({-cos(36)}, {sin(36)})} ] (d) at (c) {};
\node [ circle, draw, fill, shift = {({-cos(36)}, {-sin(36)})} ] (e) at (d) {};
\draw (a) -- (b) -- (c) -- (d) -- (e) -- (a);
\end{tikzpicture}
\end{document}
问 下图中的图象如何用tikz绘制?
