Find The Measure Of The Interior Angle Of A Regular Polygon With 9 Sides. 40n - 360 0. We can see that x and one interior angle lie on the same side of a straight line so their sum must be 180.
Interior angle sum of a pentagon 3 x 180 540. Hence the polygon has 9 sides and it is a regular nonagon. An interior angle is located within the boundary of a polygon.
N-gons so a 23 sided polygon would be called a 23-gon.
To find the sum of the interior angles you multiply 3 by 180. Find the measure of each exterior angle of a regular polygon of i 9 sides ii 15 sides. You can put this solution on YOUR website. It is also possible to calculate the measure of each angle if the polygon is regular.
