△ABC has interior angles with measures x°, 90°, and 70°, and △DEF has interior angles with measures y°, 70°, and 20°. Using the given information, which statement is true?
 A.The two triangles are not similar because x≠y .
 B.The triangles are similar because they each have an interior angle with a measure 70°.
 C.The two triangles are not similar because the interior angles are congruent but the side lengths are different.
 D.The two triangles are similar because y=90 .
