Step-by-step explanation:
1. In PQN & SRT.
a. <RST=<QPN (corresponding angle PQllSR)
b. <STR = <PNQ (corresponding angle TRIINQ)
c. TR=QN (Since TN & QN are opp. Side of parallelogram QNTR)
d. .°.PQN~=SRT.
2.PQN=PSOQ+SNO (whole part axiom)
3.SRT = SNO + NTRO(same as above)
4. PQN=SRT (From st. 1d)
or, PS0Q+SNO =SNO + NTRO (Cancellation of SNO)
or, PS0Q=NTRO
or, PSOQ +QOR=NTRO +QOR (Adding QOR on both side)
or, .°.◼️PQRS = ◼️QRTN
Best of luck!!!!.
