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

The video tutorial explains how to determine the number of sides of a polygon given the measure of one interior angle. It introduces two formulas related to the sum and measure of interior angles. The tutorial guides viewers through selecting the appropriate formula, solving for the number of sides using algebraic techniques, and verifying the solution. The example used involves a polygon with each angle measuring 108 degrees, leading to the conclusion that the polygon is a pentagon.
