Since the sum of the exterior angles of any convex polygon is 360%5Eo ,
and there are 8 congruent exterior (and also interior) angles to a regular octagon,
each exterior angle measures 360%5Eo%2F8=45%5Eo .
Since each interior angle is supplementary to the adjacent exterior angle,
each interior angle measures 180%5Eo-45%5Eo=highlight%28135%5Eo%29 ,
