Answer:
Given below is completed proof
Step-by-step explanation:
Given PQ=PR
Statement Reason
PQ≅PR Given
Point M is the midpoint of QR¯¯¯¯
Draw median PM¯¯¯¯¯¯ . Two points determine a line.
PM=PM Reflexive Property of Congruence
QM=RM Definition of midpoint
△PQM≅△PRM SSS axiom(side, side, side)
∠Q≅∠R Congruence property for triangles
Hence proved
