Final answer:
In the given equation AQPT = AARZ, the congruent side pair is b) QP = AZ.
Step-by-step explanation:
In the given equation AQPT = AARZ, we are comparing two sets of congruent sides. To determine which pair of sides is congruent, we need to identify the corresponding sides in each set. In this case:
AQ corresponds to AR
PT corresponds to RZ
QP corresponds to AZ
Therefore, the congruent side pair is option b. QP = AZ.
