Best ResponseYou've already chosen the best response.0A rule of polygons is that the sum of the exterior angles always equals 360 degrees, but lets prove this for a regular octagon (8sides). First we must figure out what each of the interior angles equal. To do this we use the formula: ((n2)*180)/n where n is the number of sides of the polygon. In our case n=8 for an octagon, so we get: ((82)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees. Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180  135 = 45). Remember that supplementary angles add up to 180 degrees.
