Understand the terminology related to right triangles: the hypotenuse is the longest side opposite the right angle, the opposite side is the side opposite the reference angle, and the adjacent side is the side next to the reference angle that is not the hypotenuse.
Identify the reference angle in the triangle, which is the angle you are focusing on besides the right angle.
Recognize that the side connected to the right angle and next to the reference angle (but not the hypotenuse) is called the adjacent side.
Recall that the opposite side is always opposite the reference angle, so it cannot be the side next to it.
Conclude that the side next to the reference angle and connected to the right angle is the adjacent side.
