In the quadrilateral PQRS, side PS is parallel to side QR. Is PQRS a parallelogram?
(1) PS = QR
(2) PQ = RS
(1) PS = QR
(2) PQ = RS

Hi,
Can someone please explain the answer A?
from both A & B each considered alone we can say that they can be rectangel, rhoumbus, IIogram or trapeizium. Hence INSUFFICIENT
Combining them also does not change the situation. HENCE INSUFFICIENT.
I would normally go for E and not A.
Cheers

well Option A says PS = QR and according to the question PS ll QR ...
hence PQ has to be equal and parallel to RS ....since connecting two equal and ll lines.
Otherwise the easiest way to find out whether it is a parallelogram or not draw two lines parallel and equal to each other and connect them with other two lines and see it will form a parallelogram
Therefore, this option is sufficient

Option B tells us that PQ = RS
Now, it does not tell us anything about PS and QR ... they can be unequal ... hence this option is insufficient to answer

Hence answer option A
