Question: are quadrilaterals abcd and efgh similar?
Answer: Yes, quadrilaterals ABCD and EFGH are similar because a translation of (x + 3, y + 4) and a dilation by the scale factor of 2 from point A′ map quadrilateral ABCD onto EFGH. No, quadrilaterals ABCD and EFGH are not similar because their corresponding angles are not congruent.
