Triangle abc has interior angles that measure x°, 90°, and 65°. Triangle def has interior angles that measure y°, 65°, and 20°. Using this information, which statement is true? question 9 options: the triangles are similar because they each have an interior angle with measure 65°. The two triangles are not similar because the interior angles are congruent but the side lengths are different. The two triangles are not similar because x ≠ 20°, and therefore there cannot be three congruent interior angles. The two triangles are similar because y = 90°.
