If it is a regular nonagon, then you use the following formula: [(s-2) x 180]/s = angle of one interior angle. (s means the number of sides) Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140. Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.
360/9 = 40 degrees
According to theorem 5.4 Every Exterior angle of a regular polygon measures 360/N so all you would do I dived 360 by the number of sides a Nonagon have which is 9
The measure of an interior angle of a regular nonagon is 140o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A nonagon interior angle is then 7 x 180o/9 = 140o.
Interior angle 177.12 degrees Exterior angle 2.88 degrees
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
Each interior angle is 140 degrees. Each exterior angle is 220 degrees.
Each exterior angle = 360/number of vertices = 360/9 = 40 degrees.Each interior angle = 180 - exterior angle = 180 - 40 = 140 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°
It is a plane area in the shape of a nonagon!
Providing it is a regular nonagon: Exterior angle: 40 degrees Interior angle: 140 degrees
The sum of the interior angles of a nonagon is (9 - 2) x 180o = 7 x 180o = 1260o In a regular nonagon, each interior angle is 1260o ÷ 9 = 140o
40 degrees
The exterior angle would have to be greater than 180 degrees. If you mean interior angle then a regular nonagon (9 sided) will have angles of 140 degrees.
