What are angles in a octagon?

Answer:
To find the interior angle of a regular n sided shape you use the following formula:
(n-2)180/n
To calculate the angle size for an octagon, which has 8 sides, you simply plug n=8 into this equation. That gives (8-2)180/8
=6x180/8
=135
Thus the angles in a regular octagon are all 135 degrees.
