Answer 2

Sorry I got confused:/
Could someone else try answering this??

Answer 3

@ParthKohli I know your itching to solve lol:)

Answer 4

It is both a rectangle and rhombus.

Answer 5

It's B ofcourse. A rhombus also has perpendicular diagonals

Answer 6

Oh yes.

Answer 7

That's why Im confused. But isn't a square a rectangle and a rhombus?

Answer 8

But @shivam_bhalla what is the angle formed with the diagonal?

Answer 9

Answer 10

Your question will stay here until you log back in

Answer 11

Oh yes, I get it.

Answer 12

@jazy , option A guarantees that it is a square

Answer 13

This forms a right angled triangle. If it already has one right angle, then there can't be another. Get it?

Answer 14

option B cannot guarantee that it is a square as a rhombus also has perpendicular diagonals

Answer 15

I realized that lol:D My first choice was B but I wasn't too sure on it since a square is also a rhombus in some cases.

Answer 16

So A?

Answer 17

I guess its B since as @shivam_bhalla says, "option B cannot guarantee that it is a square as a rhombus also has perpendicular diagonals"
