In Fig. `6.15`, angle `PQR =` angle `PRQ`, then prove that angle `PQS =` angle `PRT`.

In Fig. 6.44, the side QR of triangle PQR is produced to a point S. If the bisectors of angle PQR and angle PRS meet at point T, then prove that angle QTR =1/2 angle QPR .

In Fig 7.51, PR > PQ and PS bisects angle QPR . Prove that angle PSR > angle PSQ .

In figure, /_PQR = /_PRQ , then prove that /_PQS = /_PRT .

In quadrilateral PQRS , PS = QR and angle SPQ = angle RQP . Prove that : angle QPR = angle PQS

In Delta PQR, s is a point in QR such that angle PQS= angle SPR show that angle PSR= angle QPR

/_PQR=/_PRS, then prove that /_PQS=/_PRT

In Fig. 6.11, OP, OQ, OR and OS are four rays. Prove that angle POQ + angle QOR + angle SOR + angle POS = 360^@ .

In the given figure, PR gt PQ and PS bisects angle QPR. Prove that angle PSR gt angle PSQ .

In the given figure, PR gt PQ and PS bisects angle QPR. Prove that angle PSR gt angle PSQ .
