The sum of exterior angles is 360o. This is solved by forming an equation and solving it
Ex: what would each exterior angle of the following figures be
a) a regular octagon b) a regular 15 sided polygon
Solution: Let each exterior angle be x.
The sum of exterior angles = 360o
a) n = 8, 8x=360o, x= 360 / 8 = 45o b) n = 15, 15x = 360o, x = 360 / 15 = 14o
