### Geometry2.15 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 Directions: Solve the following probelms. Also write at least ten examples of your own.
