Question

if each interior angle of a polygon is 108 degree find number of sides.Also write the name of that polygon.

Answer 1

it will have 5 sides and the name of the polygon will be regular pentagon

Answer 2

We know that angles of a polygon are multiples of 180 deg. So looking for the least possible degree of 108, given the polygon is a regular polygon , so we get least multiple as 540 i.e. 5(108)  So the regular polygon has 5 sides.   I think the name of this polygon is pentagon
