Angles and Polygons

Question

Find the measure of each interior angle and each exterior angle of a regular 18-gon.

The measure of each interior angle is ____ , and the measure of each exterior angle is _____.

Answer 1

Hi,

sum of interior angles in a polygon = (n-2)180

n is the number of sides

find the sum of all angles using above formula. In a regular polygon each interior angle would be equal. So divide that sum by 18 to get each angle measure.

Sum of exterior angles in any polygon is 360

div that by 18 to get each angle measure
