I have noticed there is no information on this unit test so I am uploading it myself.

How would you describe the series of transformations that have occurred to move the rectangle in Quadrant IV to the rectangle in Quadrant II to show that the rectangles are congruent?
rotation, then translation
△ABC is congruent to △GHE. Describe a sequence of transformations from △ABC to △GHE that proves their congruence. (Put this in your own words)
Rotate 90* counterclockwise then make a translation from (1, 1) (3, 1) (3, 4) to (-4, 2) (-2, 2) (-2, 5). When done transforming the triangle you can see both are the exact same shape and size meaning they are congruent
Please comment if there are any mistakes good luck.
