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. What are they?*A*

Now, you should show some of your own effort. Complete the question.
