Interior Angles of Polygons

In this video, Amal Kumar explains how to find the measure of each interior angle of a regular polygon. The video covers the formula for the sum of interior angles, which is 180 degrees times (n-2), where n is the number of sides. The video then demonstrates how to calculate each interior angle by dividing the sum by the number of sides. Examples with polygons having 4, 7, and 10 sides are provided to illustrate the calculations. The video concludes with a summary of the concepts and encourages viewers to apply the formulas to find solutions.
