Question

Can we have a regular polygon whose each exterior angle is 120​

Answer 1

Answer:yes

Explanation:

the sum of the exterior angles of a polygon is  

360 ∘

for a regular polygon with n sides ∙

exterior angle  = 360 ∘ n

⇒ n =360 ∘ /exterior angle  

⇒ n = 360 /120 = 3

Answer 2

Answer:

all the exterior angles of a polygon add up to 360°, so:each exterior angle must be 360°n (where n is the number of sides). so , 360n=120;n=360120=3 it is a traingle
