In a parallelogram, opposite sides are congruent. Given that WXYZ is a parallelogram, the segment that must be congruent to segment ZV is the segment WX.
If ZV is one of the diagonals, then note that diagonals are not necessarily congruent unless the parallelogram is a rectangle or a rhombus. If ZV is a side, then WX will be congruent.
However, since you have given options for consideration as segments and have not specified them as sides or diagonals, and ZV's position is not clear enough in terms of its being a side or diagonal within specific options, the corresponding congruence can be ensured for opposite segments of the parallelogram based on what ZV aligns with.
If ZV represents a side, then the correct response for sides congruent to ZV in a parallelogram would depend directly on their location— WX in response choices alongside ZV would consistently provide the logical alignment for the side to be congruent.
Since you have not listed WX specifically among the responses, kindly clarify those segments for further accuracy. If merely focusing on your listed segments:
- ZX would be one of the sides possibly congruent, or specify more closely regarding the selection frames for final approval on congruence.
