The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.

It is a triangle because the sum of the exterior angles is always 360. We need to find a natural number n, such that 360/n=120. Of course n is 3 which means there are 3 angles. Three angles means 3 sides so it is a triangle! triangular

The sum of exterior angles always equals 360 degrees. Therefore, 360 degrees/24 angle = 15 degrees per angle. Keep in mind this only works for regular polygons.

Very rarely.

Im stuck on that too :/
