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

So if 2 opp sides are equal means it is ||gram? not matter it is square or rohbus or rectangle?

If two opposite sides are parallel and equal, then its definitely a parallelogram. It could be a square,rhombus or rectangle ( all are types of parallelogram) _________________

(1) PS = QR

(2) PQ = RS

could you please share with ur thoughts on this? and how to distinguish a square from a parallelogram in such a task?

If opposite sides of any quadrilateral are equal then its a parallelogram.But here only a is enough to determine that PQRS is a parallelogram.Bcoz PS=QR implies PQ=RS.But PQ=RS need not imply PS=QR(the isosceles trapezium).

We can't determine even using both 1 & 2 that PQRS is a square.

but square also has equal and parallel sides - i went with E since couldn't determine whether a square or a parallelogram in front of me

That is correct, but not all parallelogram are squares.

Just because the sides are the same does not make it a square. If you were given an angle, which would have to be 90 degrees, that would make it a square.

What I do is make a parallelogram with angles that are not all 90 degrees on my paper until I can prove that it is a square. If you do it that way you should not have a problem again. _________________

In the quadrilateral PQRS, side PS is parallel to side QR. Is PQRS a parallelogram?

(2) PQ = RS

I'm having a tough time seeing how this wouldn't be a parallelogram.

We know that a.) the figure has 4 sides and b.) that PS || PR. In addition, we are told that PQ=RS. I cannot construct a four sided figure with these constraints that doesn't have two pairs of parallel sides. Can someone please explain what I am missing and the logic behind how to solve these kinds of problems?

In statement 1 couldn't figure be a rectangle? Is a rectangle a type of parallelogram? I guess so right?

Thanks Cheers J

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
