Q102 of 160 Page 144

State whether the statements are true (T) or false (F).

The sum of interior angles and the sum of extreme angles taken in an order are equal in case of quadrilaterals only.

TRUE

We know that,


Sum of Interior angles of Polygon = 180(n-2)
Sum of Exterior angles of Polygon = 360


Here, we have n=4


⸫ Sum of Interior angles of Polygon = 180(4-2)=360°


And Sum of Exterior angles of Polygon = 360


⸫ The sum of interior angles and the sum of extreme angles taken in an order are equal in case of quadrilaterals only.
