How many triangles in a 13 sided polygon?

Answer 1

To determine the number of triangles that can be formed within a 13-sided polygon, we can use the formula nC3, where n is the number of vertices in the polygon. In this case, n = 13. So, 13C3 = 286 triangles can be formed within a 13-sided polygon.

Answer 2

Well, honey, let me break it down for you. In a 13-sided polygon, you can form 11 triangles by connecting the vertices. Each triangle is formed by choosing 3 vertices out of 13, which can be done in 13 choose 3 ways, resulting in 286 total triangles. So, there you have it - 286 triangles in a 13-sided polygon.
