pls answer the question pls​

Answer 1

Answer:

To Prove:- AB parallel to EF

Solution:-

Here

We know AB parallel to CD and CD parallel to EF

Also MN Is transversal

for proving two lines are parallel, we need a transversal (already MN is there), and we should prove the alternate interior angles are equal.

Thus we've to prove

APQ=QRF

I am here taking only one alternate interior angle,as you can prove others using the same.

We know

APQ=PQD (alternate interior angles)

also

PQD=QRS (alternate interior angles)

If value of PQD is x,then value of APQ & QRS = x

that is

APQ=PQD=QRS

therefore they all have equal value

then APQ=QRS

Therefore AB parallel to EF (if the pair of alternate interior angles are equal then the two lines are parallel)
