\begin{enumerate}
    \item The graph is:
    \begin{center}
    \begin{tikzpicture}                                                  
        \node[name=s, shape=regular polygon, regular polygon sides = 5,
              minimum size=4cm] at (0,0) {};

        \draw[shift=(s.corner 1)] plot[mark=*] coordinates{(0,0)} node[above] {\texttt{1}};

        \draw (s.corner 3) -- (s.corner 5):

tikz命令的结尾必须以;终止，而不是:

\documentclass{article}

\usepackage{pgfplots}
\usetikzlibrary{shapes}

\begin{document}

\begin{tikzpicture}

\node[name=s, shape=regular polygon, regular polygon sides = 5, minimum size=4cm] at (0,0) {};                                                              

\draw[shift=(s.corner 1)] plot[mark=*] coordinates{(0,0)} node[above] {\texttt{1}};

\draw[shift=(s.corner 2)] plot[mark=*] coordinates{(0,0)} node[right]  {\texttt{2}};

\draw[shift=(s.corner 3)] plot[mark=*] coordinates{(0,0)} node[below]  {\texttt{3}};

\draw[shift=(s.corner 4)] plot[mark=*] coordinates{(0,0)} node[below] {\texttt{4}};

\draw[shift=(s.corner 5)] plot[mark=*] coordinates{(0,0)} node[left] {\texttt{5}};
\draw (s.corner 1) -- (s.corner 2) -- (s.corner 3) --
(s.corner 4) -- (s.corner 5) --  (s.corner 1);
\draw (s.corner 2) -- (s.corner 5);
\draw (s.corner 3) -- (s.corner 5);
\end{tikzpicture}

\end{document}
