Find the sum (the total measure) of the interior angles of an Octagon. Show all of your work

tatiyna

One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees

so total measure of all angles in octagon = 8 * 135 = 1080 degrees
