If ABCD is a square, then AB=BC but if ABCD is NOT a square, so if it's just a rectangle, then AB and BC won't have the same length. Not sufficient.

Answer: E.

Bunuel, but the clue #1 says that ABCD is a rectangle. It is not necessary to evaluate whether it is a square or a rectangle.

I don't understand what you mean by the read part above.

As for the first statement: it says that ABCD is a rectangle, but since ALL squares are rectangles then ABCD could be a square or a rectangle which is not a square.

Ok, now I understand. I thought that, in the terminology, a rectangle could not be a "rectangle". Thanks!

Bunuel, another question:

When the question says: Together with point D, A, B, and C form a rectangle. Is there a specific order in which the points are set? For example, if we start in the left lower vertex of the rectangle as Point A and then continue to the left upper vertex as point B, and so on....¿would it be the correct order?

In general, when the GMAT says, for example, "a triangle ABC....", is there a specific vertex in which we should start and a orientation that we have to follow?

Generally when we are given "quadrilateral ABCD" or "triangle PQR", then it means that vertices are in that particular order only.

I got little confused.......it is said that together with D, A, B, and C form a rectangle.....doesn't that mean AB and BC are not equal??

All squares are rectangles, so if ABCD IS a square then AB=BC. Look at the figures below:

The first figure is a rectangle which IS a square, so in this case AB=BC and the second figure is a rectangle which is NOT a square, so in this case AB#BC.

Hope it's clear.

Sorry Bunuel for picking on this..just want to be completely sure. So unless it's specified that the figure is a square (or it forms a square), we are to assume that a rectangle means both a square and non-square?

If it's given that a figure is a rectangle, then it could be a square because all squares are rectangles (but not all rectangles are squares).

Generally when we are given "quadrilateral ABCD" or "triangle PQR", then it means that vertices are in that particular order only.

But the real question is what is the order? Like for a triangle for example is P upper vertex then Q for the left vertex and R for the right vertex? And in a square do we go clockwise? Anticlockwise?

Thanks Cheers J

Square ABCD means that the order of the vertices is A, B, C, D. Usually it does not matter whether you go clockwise or anticlockwise.
