Answer

\(\boxed{10}\) is the final answer.

Steps

Step 1 ：A polygon with n sides has n vertices. From each vertex, we can draw a line to every other vertex except itself and the two adjacent vertices.

Step 2 ：Let's consider a 13-gon. It has 13 vertices.

Step 3 ：From each vertex of a 13-gon, we can draw \(13 - 1 - 2\) diagonals.

Step 4 ：Performing the subtraction, we find that from each vertex of a 13-gon, \(10\) diagonals can be drawn.

Step 5 ：\(\boxed{10}\) is the final answer.
