Geometry
2.15 Problems on Exterior Angles of a Regular Polygon - I

Example:
Find the measure of each of the exterior angle of a regular polygon of 5 sides.
Solution:
Given that, n = 5 sides
Each exterior angle of a regular polygon on 'n' sides = 4/n rt.angles or 360/n.
= 4/5 * rt.angles
= 4/5 * 90 degrees
= 4 * 18 degrees
= 72 degrees.

Example:
Find the measure of each exterior angle of a regular hexagon.
A hexagon has 6 sides, so n = 6
The measure of each exterior angle of a regular hexagon = 360/60 = 60
= 60 degrees
