Standard : IXUnit : POLYGONSTopic : Sum of interior angles

The geometric shapes having equal number of sides and angles are called polygons

SUM OF ANGLES

Polygon Sum of angles

(3-2) 1800

(4-2) 1800

(5-2) 1800

(6-2) 1800

Polygon Sum of angles

180 x 3 = 5400

180 x 4 = 7200

180 x 5 = 9000

180 x 6 = 10800

5400 1800 540-180=3600

7200 3600 720-360=3600

9000 5400 900-540=3600

10800 7200 1080-720=3600

SUM OF EXTERIOR ANGLES OF A POLYGON IS 3600
