1. The problem asks to match the sides of a right triangle relative to the angle $\theta$. 2. In a right triangle, the hypotenuse is always the longest side opposite the right angle. 3. The side opposite $\theta$ is the side directly across from angle $\theta$. 4. The adjacent side is the side next to $\theta$ that is not the hypotenuse. 5. Therefore, relative to $\theta$: - Hypotenuse: the longest side opposite the right angle. - Opposite: the side opposite $\theta$. - Adjacent: the side next to $\theta$ but not the hypotenuse. This matches the description given in the problem.
