Keeping this in view, how many sides are in the Nonagon?
It has four equal sides and four right angles, each measuring 90 degrees. A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each.

What is the interior and exterior angle of a regular Nonagon?
The sum of the exterior angles of any polygon is 360 degrees. 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.
