How to Calculate the Interior Angles of a Regular Octagon.?


1. Draw two lines from one point of the octagon to the other point directly across, creating a rectangle and two trapezoids. Then split the rectangle by the diagonal and the trapezoid from one of its base points to the opposite corner. This will
