For your info :

            120 degrees is  1/3  arc of a circle   without  any  "if".



Therefore,  the entire first part of the first sentence,  from its first word until the comma - is EXCESSIVE.

When you formulate the problem in a way as you do it,  you simply demonstrate that you don't know the subject.
