+1678 The sum of interior angles of a regular polygon is 540 degrees. Find the measure of each interior angle of the polygon.
+108 Any polygon with interior angles that add up to 540 must have 5 sides and 5 corners (a pentagon). Assuming it is a regular pentagon, you need to work out what 1/5 of 540 is, which is the same as dividing it by 5. 540/5 = 108. This is the number of degrees in one interior angle of a regular pentagon.
