The correct option is A ∠PTQ=∠RSQ,
∠TQP=∠SQR,
∠QPT=∠QRS
Consider △TPQ and △SRQ
Given that
TQ = SQ
PQ = QR
TP = SR
Hence both the triangles are congruent by SSS criterion for congruency of triangles.
By using corresponding parts of congruent triangle criteria, we observe,
∠PTQ=∠RSQ,
∠TQP=∠SQR,
∠QPT=∠QRS
