Find the measure of each interior angle and each exterior angle of a regular 20-gon (a twenty-sided polygon).Measure of each int
ra1l [238]

Given a regular 20-gon ( a 20 sided polygon )

The measure of each interior angle will be given by:

\frac{(n-2)}{n}\cdot180

where n is the number of sides

Substitute with n = 20

So, the measure of each interior angle =

\frac{20-2}{20}\cdot180=\frac{18}{20}\cdot180=162

The sum of exterior angles = 360

So, the measure of each exterior angle = 360/20 = 18
