23.What is the missing piece of information required to provethese triangles congruent?a) QYQYb) NYPYC) ZN 2 Pd) QY is the perpendicular bisector


In this case, the information that is explicitly seen in the graph is that we have 2 pairs of equal sides.
The missing information, that can also be seen in the picture, is that we have a shared side that is QY.
If we applied the reflexive property, we know that:
[tex]QY\cong QY[/tex]and then we know that we have 3 pairs of equal sides, what proves that the triangles are congruent.
Answer: QY = QY (Option A).
