Learn to find the number of sides of a regular polygon when given one exterior angle

The video tutorial explains how to determine the number of sides of a regular polygon when given one exterior angle, specifically 30 degrees. Initially, it mentions a method involving finding the interior angle, but then introduces a simpler approach. This method involves dividing the total sum of exterior angles, 360 degrees, by the given exterior angle, 30 degrees, to find the number of sides, which results in a 12-sided polygon. The tutorial concludes by confirming that all exterior angles are equal in a regular polygon.
