Is the quadrilateral ABCD a square?
(1) All four sides of ABCD have the same length.
(2) Two of the adjacent angles of ABCD add up to 180 degrees.
Kudos for a correct solution.
Statement 1, tells us that ABCD can be a Square OR a rhombus. Therefore IS.
Statement 2, tells us nothing new about what we already know about any quadrilateral. Adjacent angles add up to 180. This can be a Rhombus or Square.
Answer E.
I am having slight confusion in statement 1,All squares are both rhombus and rectangles.That's what I read in GMAT mathclub book.
So,if a square is also a rhombus.Then,the answer to the question:is the quadrilateral ABCD a square? would be "NO".Isn't it?
So the answer should be A.
What am i missing here?
