I had a tougher time solving the tests than creating them, which is probably a good sign. I chose tests that would yield an simple angle of 0 (12:00), positive and less than 180 (1:30), exactly 180 (6:00) and negative (4:00). If I have any code questions, I'm wondering if there's any way to refactor the code in the angle function, especially the 12 --> 0 part and the use of absolute value multiple times.
