1) triangle PQS = triangle QRS , not relate to its definition (quadrilateral PQRS can be parallelogram or not parallelogram such as kite, trapezoid or others) --> not suff

technocrat · Answer

A
In parallelogram diagonals bisect it in equal areas.

mrsmarthi · Answer

I think ans might be E. Not only a parallelogram, even the Trapeziod diagnol also bisect the area of the quadrilateral. For a Parallelogram, we need to know that opposite sides are parallel. And this information is not provided in either of the clues.

Economist · Answer

I go with C. 
From 1 and 2 it should be a square or a rhombus and both of them are parallelograms.
What is OA?

icandy · Answer

To be able to say that a Q is a P

(1) opposite sides are parallel and equal

(2) opposite angles are equal.

I am not seeing how I can say that PQ=RS and QR=PS.

I got E. What is OA & OE?
