Answer 1

Answer:

In the given figure,

Δ OPQ and ΔOBC are congruent to each other as,

BC/PQ = OC/OQ

Now, ΔRPQ and ΔRAD are congruent to each other because

AD/PQ = DR/QR

Also, it is given in the question that ABCD is a parallelogram.

Hence, BC = AD

Now, ΔQOR and ΔQCD are congruent because,

OC/OQ = DR/QR

Hence, CD║OR.

Hence proved.
