Answer 1

Answer:

Step-by-step explanation:

join EF

In triangle POQ, by basic propotionality theorem,

PE/QE =PD/OD...............(1)

Similarly, in triangle POR

By basic propotionality theorem

PD/OD=PC/CR..............(2)

from(1) and (2)

PE/QE=PC/CR

So, in triangle PQR, by converse of BPT,

EF parallel QR

Hence proved
