Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
Each exterior angle: 40 degrees Each interior angle: 140 degrees
Exterior angle 40 degrees Interior angle 140 degrees
It is 360/9 = 40 degrees.
The measure is 360/9 = 40 degrees.
360/9 = 40 degrees
The sum of the interior angles of a polygon is 2n-4 Right Angles For a nonagon (2x9)-4 RAs = 14x90°=1260° To find the interior angle of a regular nonagon, divide this by 9 which gives 140° To find the exterior angle, subtract this from 180 and you get 40°. The sum of the exterior angles of a polygon is 360°, so for a regular polygon you can also divide this by the number of sides, which in this case also gives: 360° ÷ 9 = 40°
140 degrees is.
Each interior angle measures 140 degrees
