21+ What Is The Sum Of The Interior Angles Of A Nonagon
Background. Take any vertex and connect it to all other vertices of the polygon. If you have a nonagon you can join one corner with 7 others by straight lines passing through the interior of the nonagon.

The number of triangles is always two. Nonagon is a 9 sided polygon. Notice that the angle measures in the first line of our equation is just a rearrangement of the measures of the interior angles of the three triangles.

Can you describe 2 ways to prove that the sum of the interior angles of a triangle is 180 degrees.

A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides. Sum of interior angles of a regular polygon and irregular polygon: Learn how to find the sum of the interior angles of any polygon. Find the sum of the interior angles of each convex polygon.
