Understanding Interior Angles of Polygons

This video tutorial from Moomoomath explains how to calculate the sum of interior angles in polygons using the formula (n-2) * 180, where n is the number of sides. The video provides examples with triangles, hexagons, pentagons, and heptagons, demonstrating how to find the sum of interior angles and the measure of each angle. The tutorial concludes with a prompt to subscribe for more math and science videos.

What is the sum of the interior angles of a triangle?
