A quadrilateral is parallelogram if,

1.It has 2 pairs of ||el sides

2.It has 2 pairs of opposite sides if equal lengths

3.It has one pair of opposite side which are parallel and equal length.

stmt1,

PS||QR and PS=QR. PQRS is parallelogram

Suff

stmt2,

PQ=RS.We don't know if this 2 sides are parallel or we don't know another pair of opposite side is equal..

Insuff

Pick A

Glad you posted this problem. I got this one in the practice test this weekend and am not very convinced with the OA. Hopefully we see some smart ways to solve this problem.

From statement 1, you can come to know that one pair of opposite sides parallel n congruent..
But as per ||gram definitn, you need to have two pairs of sides equal and parallel..
Selango,
Can you explain a bit more...

46 on Quant, 30 on Verbal. This was saturday when I took MGMAT test.
Then took GMAT Prep on Sunday. 44 Q, 32 V. Total score stayed the same.

What about you?

I had the exact same reason for not picking A. I ended up picking E, cuz we still don't know if the equal side are parallel to each other or not.
