--------------------------
Let's say the angle is 120 degrees.
------------
Then its corresponding exterior angle is 180-120 = 60 degrees
------------
That means every exterior angle is 60 degrees.
--------------
Important point: The sum of ALL the exterior angles is ALWAYS 360 degrees.
---
# of exterior angles is 360/60 = 6
----
Therefore # of sides is 6.
