The interior angles of an octagon add up to 1080 degrees
An octagon has 8 sides and the sum of its interior angles add up to 1080 degrees.
All angles of an octagon must add up to 1080 degrees. A "regular" octagon has all equal angles, which are all 135 degrees. Other angles are possible though. As long as the shape has 8 sides and all angles add up to 1080, it is still classified as an octagon.
