# 6.(a) What is the minimum interior angle possible for a regular polygon? Why? (b) What is the maximum exterior angle possible for a regular polygon?

(a) A regular polygon of 3 sides i.e, equilateral triangle has the least measure of an interior angle= $$60^{\circ}$$.
(b) Since the minimum interior angle of a regular polygon is equal to 60°, therefore, the maximum exterior angle possible for a regular polygon = $$180^{\circ} – 60^{\circ} = 120^{\circ}$$
