For the last one, how are you supposed to know which one is a, b or c??

[@theanimationmaster724]

The values are interchangeable, and it doesn’t matter what order you put them in, as long as a capital A represents and angle and a normal a represents a side, it won’t make a difference if they’re re-arranged.
