Prove that the sum of the exterior angles at opposite vertices of any quadrilateral es equal to the sum of the interior angles at the other two vertices.
THIS question is REAly really really really getting me frustrated...
The way we're suppost to do it is like this...
180n-360 is the interior angles and exterior angles is 180n-180(n-2)
From there I don't know...
