The three interior angles of ∆JKL measure 45°, 45°, and 90°. The three interior angles of ∆PQR measure 45°, 45°, and 90°. The side JK of JKL measures 4 cm. Based on the given information, which of the following must be a true statement?

Explanation

Similar triangles have the same angle measures. Congruent triangles have the same angle measures and the same side lengths. From the given information, you cannot know if the side lengths are the same, so you can conclude only that the triangles are similar.
