Final answer:
The transformations that make A'B'C'D' congruent to ABCD are translation and reflection.
Step-by-step explanation:
The transformations that make A'B'C'D' congruent to ABCD are translation and reflection.
A translation is a transformation that moves each point of a figure the same distance in the same direction. In this case, ABCD is translated up by 4 units to obtain A'B'C'D'.
A reflection is a transformation that flips a figure over a line, in this case, the y-axis. By reflecting ABCD about the y-axis, we obtain A'B'C'D', making the two figures congruent.
