Final answer:
The correct transformation to prove that rectangle ABCD is congruent to rectangle KLMN is translation.
Step-by-step explanation:
The correct transformation to prove that rectangle ABCD is congruent to rectangle KLMN is translation.
A translation is a transformation that moves all the points of a figure the same distance in the same direction.
In this case, if rectangle ABCD can be moved to coincide with rectangle KLMN by sliding it without any rotation, reflection, or dilation, then the correct transformation is translation.
