How do I know which sides are the Adjacent, Opposite and Hypotenuse for trigonometry?
The hypotenuse is the easiest to spot - it's always the longest side, and it's across from the right angle in the triangle. This leaves two others: the adjacent side is the side that is next to the acute angle the question is concerned with, and the opposite side is the side that's literally opposite that angle.
