Determine the measure of each exterior angle of a regular octagon

The video tutorial explains how to find the measure of each exterior angle in a regular polygon, specifically an octagon. It emphasizes that the sum of all exterior angles in any polygon is always 360 degrees. The tutorial guides through the process of calculating the measure of one exterior angle by dividing the total sum by the number of sides. It also clarifies the concept of regular polygons, where all angles and sides are equal, and demonstrates the calculation using an octagon as an example.
