△abc has interior angles with measures 130°, x°, and 15°, and △def has interior angles with measures 35°, 15°, and y°. using the given information, which statement is true?
1) the triangles are not similar because x≠y .
2) the triangles are not similar because x≠15 .
3) the triangles are similar because they each have an interior angle with measure 15°.
4) the triangles are similar because y=130 and there are three pairs of congruent angles.

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
