Answer:
Yes they are congruent
Step-by-step explanation:
You know this because of the angle that is marked. You can also know this because of the length of the sides and how its only a rotation of 180 degrees
Well, anything that's rotated (turned), reflected (flipped), or translated (moved) is still the same shape of the same size, so the new figures would be congruent with the originals. Dilation, however, is when the shape stays the same but the size changes, so when a figure is dilated, it's not congruent, just similar. 2 out of the 4 are dilated, so those ones would be the answer.
The answer to y-3=4/7(x-7) is y=4/7x-1
