In the construction of the perpendicular bisector of a given line segment, as shown in the figure below
ΔPMA≅ΔPMB by which congruence criterion?
The correct option is D. SAS
Consider ΔPMA and ΔPMB
PM=PM (Common is side)
MA=MB (PQ is perpendicular bisector of AB)
∠PMA=∠PMB=90∘ (PQ is perpendicular bisector of AB)
Thus, by SAS congruence, ΔPMA≅ΔPMB
