What is the measure of each interior angle of a rectangle octagon? WILL MEDAL!!! A. 135 B. 1080 C. 147 D. 124

OpenStudy (anonymous):

135, because the sum of all interior angles in polygon increase with 180 degrees as each side is added. e.g. triangle is 180, quadrilateral (like square) is 360, pentagon is 540, hexagon is 720, septagon is 900, and octagon is 1080. therefore 1080/8 = 135
