class 8 maths Exercise 3.2 Question no 2

Q2 :
Find the measure of each exterior angle of a
regular polygon of

(i) 9 sides

(ii) 15 sides


Answer :

(i) Sum of all exterior angles of the given polygon = 360 º

Each exterior angle of a regular polygon has the same measure.

Thus, measure of each exterior angle of a regular polygon of 9 sides
= 360/9  = 40
(ii) Sum of all exterior angles of the given polygon = 360 º
Each exterior angle of a regular polygon has the same measure.
Thus, measure of each exterior angle of a regular polygon of 15 sides
=360/15  = 24
