The video tutorial explains how to calculate the measure of an interior angle of a regular polygon when given the sum of all its interior angles. It introduces the formula for the sum of interior angles, which is (n-2) * 180, where n is the number of sides. The tutorial demonstrates how to solve for n when the sum is known and then how to find the measure of one interior angle by dividing the sum by the number of sides.
