Given the sum, find the meausre or a single interior angle of a regular polygon ex 1

The video tutorial explains how to find the measure of an interior angle in a regular polygon given the sum of all interior angles. It introduces the formula for calculating the measure of an interior angle and demonstrates how to determine the number of sides of a polygon when the sum of its interior angles is known. The tutorial then shows how to calculate the measure of each individual angle by dividing the sum by the number of sides. The process is summarized with an example of a polygon with a sum of 720 degrees, resulting in each angle measuring 120 degrees.
