How do you find the exterior angle of a shape
WebSep 27, 2024 · The exterior angle is supplementary to the interior angle, so to find the exterior angle, we simply subtract the interior angle from 180: 180 - interior angle. If we add up all of our exterior ... WebEach exterior angle of a regular nonagon has an equal measure of 40°. Symmetry in a regular nonagon A regular nonagon has 9 lines of symmetry and a rotational symmetry of order 9, meaning that it can be rotated in such a way that it will look the same as the original shape 9 times in 360°.
