Approximately how many degrees are in the measure of an interior angle of a regular eight sided polygon? Will award medal!

OpenStudy (carlyleukhardt):

For regular polygons, all the interior angles are the same measure, while the sum of the exterior angles is always 360 for any regular polygon. Use these facts and the fact that each interior/exterior angle pair has a sum of 180 to answer this question. 360 divided by 8 = 45. So each exterior angle of the figure measures 45. 180 - 45 = 135, so each interior angle measures 135 degrees :)
