ANSWER

In △ABC,P and Q are mid points of AB and BC respectively.

So, PQ∣∣AC and PQ=

1

AC ..................(1) (Mid point theorem)

Similarly, X and Y are mid points of sides CD and AD respectively.

we get

PQ∣∣XY and PQ=XY

Hence, PQXY is a parallelogram .... (pair of opposite sides is parallel and equal)

Now, XY∣∣AC and QY∣∣BD

And diagonals in PQXY are equal

Then PX=QY

Answer 2

pq l l xy

pq= xy
