What is the name of the geometric figure that has 9 sides?
An enneagon is a polygon with nine sides and nine vertices.
What are polygon figures?
In geometry, a polygon is a plane geometric figure and is composed of a finite sequence of consecutive straight segments that enclose a region in the plane. These segments are called sides, and the points where they intersect are called vertices. The polygon is the two-dimensional case of the polytope.

How to make a Tridecagon step by step?
To do this, it is necessary to divide the circumference into 13 equal parts and then connect each vertex with a line segment, corresponding to each side of the tridecagon. One way to build a regular tridecagon, although not the only one, is by drawing the lines as shown in the following animation: Figure 3.
