There's a really handy little formula. The total number of degrees in a polygon (the sum of the interior angles) is equal to (2n-4) right angles or (2n-4)x90 degrees.
So for an octagon, the sum of the interior angles is 2x8-4 right angles = 16-4 right angles = 12 right angles or 12x90 degrees = 1080 degrees. To find one angle, divide this by 8 and you get 135 degrees.
