Determine the number of sides of a polygon when given the sum of interior angles ex

The video tutorial explains how to determine the number of sides of a polygon when given the sum of its interior angles. It introduces the formula for the sum of angles in a polygon, which is (n-2) * 180 degrees, where n is the number of sides. The tutorial demonstrates how to solve for n when the sum of the angles is 1440 degrees, leading to the conclusion that the polygon is a decagon with 10 sides.
