Question

In PQR, PQ=PR M is a point on PQ and the line through M intersect PR at O and QR extended at N Prove PO>PM​

Answer 1

Answer:

We have, PM=15cm,NR=8cm,PQ=25cm and PR=20cm

Now, 

MQ=PQ−PM=25−15=10cm and PN=PR−NR=20−8=12cm

Hence, 

MQPM=1015=23

Also, 

NRPN=812=23

∴  MN∥QR      [ By converse proportionality theorem ]
