The sum of the interior angles of a shape is 720 degrees. what shape is this? what is the answer? how would keith come up with his solution? show your work.
Sum of interior angles of a polygon = (n-2)180 [where n = no. of sides] (n-2)180 = 720 n-2 = 720/180 = 4 n-2 = 4 n = 4+2 = 6 So it is a 6 sided shape (Hexagon)
