The video tutorial explains how to calculate the interior angles of regular polygons, specifically focusing on octagons and nonagons. It begins by introducing the formula for the sum of interior angles and demonstrates how to apply it to find the angle of a regular octagon. The tutorial then transitions to calculating the interior angle of a regular nonagon, using the same principles. The key takeaway is understanding the method to find individual interior angles of regular polygons by dividing the total sum of angles by the number of sides.
