Is ABCD a square ?
1. ABCD is a trapezium.
2. ABCD is not a rhombus.
I chose "D". My explanation goes like this.
1. If ABCD is a trapezium then it can never be a square. So this is SUFF.
2. ABCD is not a rhombus. This also implies that ABCD can never be a square ( All squares are rhombus but all rhombus are not squares ). --SUFF
But the answer is not D. (Source - MBA quantitative aptitude -- McGraw Hills Publication)
Am I missing something. Would like to know your responses.
Thanks

agree with you. there is no reason that 2 doesnot work. if abcd is not a rhomus, it is not a square cuz square a special type of rhobus. the given quadilateral can be a ractangle but cannot be a square.
D is it.
