Finding the Sum of Interior Angles of Polygons

Find the sum of interior angles by dividing the polygon into triangles. Remember this - since the sum of the interior angles in a triangle is 180°, the sum of a polygon's interior angles is the product of the number of triangles in the polygon and 180.
