Front

How do you identify the opposite side in a right triangle?

Back

The opposite side is the side opposite the angle of interest (Theta).

Front

How do you identify the adjacent side in a right triangle?

Back

The adjacent side is the side next to the angle of interest (Theta) that is not the hypotenuse.
