Find the measure of each exterior angle of a regular polygon of
(i) 9 sides
(ii) 15 sides
(i) Since, 9 sides of polygon has 9 angles
And we know that:
Sum of all exterior angles of a polygon = 360o
Each exterior angle of a regular polygon has the same measure
Therefore,
Measure of each exterior angle of a regular polygon of 9 sides =
= 40o
(ii) Sum of all exterior angles of the given polygon = 360o
Each exterior angle of a regular polygon has the equal measure
Thus, measure of each exterior angle of a regular polygon of 15 sides =
= 24o
