WebSince the sum of exterior angles of any polygon is always equal to 360°, we can divide by the number of sides of the regular polygon to get the measure of the individual angles. For example, for a pentagon, we have to divide 360° by 5: 360°÷5 = 72°. Each exterior angle in a regular pentagon measures 72°. In the following table, we can see ... WebIf the sides of the convex polygon are increased or decreased, the sum of all of the exterior angle is still 360 degrees. We add all the known angles: 110°+140°+100°+120°+150° = … esus orleans
