In a regular polygon having 10 sides, all sides are same size and measure of all interior
Angles are
Same.
The sum of interior angles of polygon is
(n-2) × 180o where n is the number of sides of polygon.
(10-2) × 180o =1440 o here n=10
Each interior angle= 1440/10 = 144o
(ii) In a regular polygon, all sides are same size and measure of all interior angles are
Same.
The sum of interior angles of polygon of 15 sides is
(n-2) × 180o where n is the number of sides of polygon.
(15-2) × 180o =1440o here n=15
Each interior angle= 2340/15 = 156o
