this may sound kinda dump but I was trying to figure out how to read the angles. In this question it ask about angle BCA, how do I know which angle is ABC, BCA, or BAC?

Whatever the middle alphabet is, that is the point where angle develops.

BCA means the angle that develops from the point C

Well its the angle on the middle letter i think. BAC would be angle on A and BCA would be on C.
