Number of Diagonals In a Regular Polygon - Geometry

This geometry video tutorial explains how to calculate the number of diagonals in a regular polygon such as a square, pentagon, hexagon, heptagon, and an octagon. It also explains how to confirm the answer by drawing the diagonals in a regular polygon. In addition, it discusses how to determine the type of polygon given the number of diagonals as well as the sum of the interior angles of a polygon and the measure of each interior angle and exterior angle.

    Mr. Organic Chemistry Tutor, thank you for another incredible video/lecture on the Number of Diagonals In a Regular Polygon. From the different shapes in Plane/Solid Geometry, it's really good to know how to calculate the diagonals of each shape and also the interior/exterior angles.

    This could be used in architecture if you ever need support beams in an irregular polygon, as the number of diagonals aren't always apparent.

    Why do you use 3 in the formula for the heptagon? I get it arrives at the correct answer...but why do you use 3 instead of 4?
