Question

Prove PQ//AC...

Please refer to the attachment!!!!

Answer 1

In ∆ ABD

AD//PM

Therefore, using mid-point theorem,

P is the mid - point of AB and M is the mid point of BD.

In ∆ BDC

MQ//CD

Therefore, using converse mid - point theorem,

Q is the mid point of BC.

Now,

In ∆ ABC

Q is the mid point of BC and P is the mid point of AB.

Using mid - point theorem

So, PQ//AC.

Hence proved.
