Answer 2

1. In triangle ABC,

 P and Q are midpoints of AB and BC

So, PQ ll AC and PQ = AC ---------------------------------------------------1

In triangle ADC,

S and R are midpoints of AD and DC respectively

So, SR ll AC and SR = 1/2AC---------------------------------------------------2

from 1 and 2,

PQ ll AC and PQ = SR

So, PQRS is a parallelogram.

Hence proved
