There are 20 triangles inside a 22 sided polygon
To calculate the number of triangles that can be formed by connecting the vertices of a 20-sided polygon, we can use the formula n(n-1)(n-2)/6, where n is the number of vertices. For a 20-sided polygon, n = 20, so the formula becomes 20(20-1)(20-2)/6 = 1140. Therefore, you can fit 1140 triangles within a 20-sided polygon.
The total angles will be 3600 degrees, because each triangle will have 180 degrees total.
