Two students describe the sides of right triangle ABC in relation to ∠B.

Triangle A B C is shown. Angle A C B is a right angle.
Tomas
AB is the hypotenuse.

AC is the opposite side.

BC is the adjacent side.

Iliana
AB is the hypotenuse.

BC is the opposite side.

AC is the adjacent side.

Who is correct? Explain.

Tomas is correct; AC is opposite ∠B and BC is adjacent to ∠B.
Iliana is correct; BC is opposite ∠B and AC is adjacent to ∠B.
Both are correct because both AC and BC are opposite ∠B.
Neither is correct because neither AC nor BC is opposite ∠B.

Tomas is correct.

Reason: The hypotenuse is the side opposite the right angle C, which is AB. For angle B, the side across from B is AC (so AC is the opposite side) and the other non‑hypotenuse side meeting B is BC (so BC is the adjacent side). Iliana swapped the two.
