1. Triangle ABC is dilated using D as the center of dilation with scale factor 2. The image is triangle $$A′B′C′. Clare says the two triangles are congruent, because their angle measures are the same. Do you agree? Explain how you know.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
