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

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
hence PQ has to be equal and parallel to RS ....since connecting two equal and ll lines.

Hi J,
You are Right.
Actually, the statement 1 could well yield
a simple parallelogram or a rectangle or a rhombus or a square.
All these are types of parallelogram:
Simple parallelogram - a quadrilateral with opposite sides equal and parallel
Rectangle - a parallelogram with adjacent sides at 90 degrees
Rhombus - a parallelogram with all sides equal
Square - a parallelogram with adjacent sides at 90 degrees and all sides equal
Kudos is the best form of appreciation
