Interior Angles of Polygons

The video tutorial explains how to calculate the sum of interior angles in any polygon using a formula. It begins with an introduction to interior angles and demonstrates the calculation using a pentagon. The formula, n-2 times 180, is introduced to find the sum of interior angles. The tutorial also covers finding one interior angle in a regular octagon by dividing the sum by the number of sides. The video emphasizes understanding the formula and its application to different polygons.
