I'm really needing help with this problem. Thanks! Coplanar points A, B, C, and D are noncollinear. How many distinct angles do they determine? Name the angles.

It would far better to state that "no three of which are collinear". An angle is the union of two rays which have a common end-point. Thus there are three angles that have vertex A. What are they?
