Answer:
51) D. a dilation by a scale factor of 1/2 with the origin as the center of dilation.
44) B. The angles measures of △ A'B'C' are the same as those of △ ABC, but the side lengths of △ A'B'C' are half the size of those of △ ABC
Step-by-step explanation:
51) option D is the only one that changes the shape of the figure, which is the only way it wont be congruent
44) angles don't change when the figure is rotated or dilated. the shape is half the size, so the sides are half as long.
i got you! idk why i'm doing this but i know if i was your age this would have made my day. you're only 15 so don't take life too seriously, take lots of risks, and always take the easy way out <3
