How to determine the number of sides of a regular polygon given one interior angle

The video tutorial explains how to calculate the measure of one angle in a regular polygon using the formula (n-2) * 180 / n. It discusses the meaning of variables M and N, where M represents the measure of an angle and N represents the number of sides. The tutorial then demonstrates solving for N when the measure of one angle is given as 120 degrees, resulting in a polygon with six sides. The session concludes with a recap and encouragement for students to note down the solution.
