Hi Diya
Given :-exterior angle is 72°
There is a formula for the exterior angle measurement of regular polygons, where n is the number of sides and the measure of each exterior angle:=360°/number of sides
each exterior angle = 360°/n
72° = 360°/n : Multiply both sides by “n” to clear the fraction
(72°)(n) = 360° : Divide both sides by 72° to isolate n.
n = 360°/72°
n = 5 sides, this is a pentagon. ANS
