It is a triangle, because the sum of the exterior angles is always 360. We need to find a natural number n, such that 360/n=120. Of course n is 3 which means there are 3 angles. Three angles means 3 sides so it is a triangle! Or triangular.

Hope this helps u get through ur question easily !!! ^_~ !!!
