How to determine the number of sides of a polygon when given the sum of interior ang

The video tutorial explains how to determine the number of sides of a polygon given the sum of its interior angles. It starts by introducing the formula for the sum of interior angles and then demonstrates how to solve for the number of sides using a given sum of 1260 degrees. The process involves simplifying the equation through the distributive property and basic arithmetic operations. The tutorial concludes by identifying the polygon as a nonagon, having nine sides.
