Frequently Asked Questions
What is the exterior angle of nonagon?
40 degreeAnswer: The measure of an exterior angle of a regular nonagon is 40 degree.
How do you find the measure of an exterior angle of a nonagon?
Answer: heyyy, Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees.
How do you find the external angle?
The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
Can you find the exterior angles of any irregular nonagon?
You cannot find the exterior angles of any irregular nonagon. If it is a regular one, then you can. A regular nonagon has 9 sides and so 9 exterior angles all of which are equal to 360/9 = 40 degrees. The interior angle = 180 - 40 = 140 degrees.
What is the sum of the angles of a nonagon?
The sum of the measures of the exterior angles of a nonagon is 360°. A nonagon is a 9-sided polygon, however, the number of sides of a polygon... See full answer below. Become a Study.com member to unlock this answer! The sum of the measures of the exterior angles of a nonagon is 360°.
What is the interior angle of a nonagon polygon?
Nonagon is one of the types of polygonal shapes. The nonagon is said to be a 9 sided polygon. It is also called Enneagon. The polygon sides are always straight and it is said to be a two dimensional shape. The interior angle of the regular polygon is 140 degree.
