Question

What is one exterior angle of a regular 16-gon measures?

Answer 1

`22.5^0`

Explanation:

for any regular polygon the exterior angles add up to `360^0`

so `"1 "ext./_=360/n " where "n=" the number of sides"`

for a 16-gon`1 " ext. /_=360/16=22.5^0`

If you wanted the size of 1 interior angle subtract this from `180^0`

thus: `1 " int."/_=180-22.5=157.5^0`
