△abc has interior angles with measures x°, 100°, and 70°, and △def has interior angles with measures y°, 70°, and 20°. using the given information, which statement is true? the triangles are similar because they each have an interior angle with a measure 70°. the two triangles are not similar because x≠y . the two triangles are not similar because y=90 so it is impossible to have three congruent angles. the two triangles are not similar because the interior angles are congruent but the side lengths are different.
