Is quadrilateral Q a square?
(1) The sides of Q have the same length.
(2) The diagonals of Q have the same length.

I think that answer should be A
But it is given as c

Great thanks for the reply.

Also for those who want to know area of a rhombus is 1/2(diag1+diag2) - whcih can also mean the diagonals are of different lengths.

Special case obviosuly being a square with both diagonals of the same lenght as well as the all sides of same length.

Correcting slip by ausgmat2008,

Pls read area of a rhombus as 1/2 (diag1 * diag2) [ half of the product of diagonals ]
I am on a break !!
