Square?

[Mclaughlin]

E, F, G, and H are the vertices of a polygon. Is polygon EFGH a square?

(1) EFGH is a parallelogram.

(2) The diagonals of EFGH are perpendicular bisectors of one another.

I think the asnwer can be E..

Statement 1 is not sufficient, since a rectangle can also be called as a parallelogram.

Statement 2 alone is also not sufficient, since the same conditions can be said for a rectangle.

Both together do not give any additional information..hence E

A rectangle doesn't have perpendicular bisectors (unless it's a square, of course).

However, both statements could be describing a rhombus, so the answer is in fact (e).

Thanks Stuart for correcting me. Everytime I come across you, i am getting a valuable input from you.......
