Question

is it possible to have a regular polygon each of whose interior angle is 120 degree​

Answer 1

Answer:

Since, answer is not a whole number, thus, a regular polygon with measure of each interior angle as 22⁰ is not possible. ... This can also be proved by another principle; which states that each exterior angle of a regular polygon is equal to 360 divided by number of sides in the polygon. If 360 is divided by 3, we get 120.
