WebThe sum of interior angles of decagon is. (n−2)×180 o where n is number of sides of polygon. (10−2)×180 o=1440 o here n=10 because deca means 10. Each interior angle =1440/10=144 o. As we know that the sum of interior and exterior angles is 180 o. Exterior angle + interior angle =180 o. Exterior angle +144 o=180 o. WebThe sum of interior angles is \((6 - 2) \times 180 = 720^\circ\).. One interior angle is \(720 \div 6 = 120^\circ\).. Exterior angles of polygons.
