because the opposite sides seem to be ||

4 sides equal

Answer 9

If all the 4 sides of a ||gm are equal, them it makes a rhombus!

Answer 10

Look, both rectangle and squares are ||gms ..

And, a square is a rhombus too!

Answer 11

@Colcaps I think you've missed something out of the description. This could be any four sided shape. If there's no more information, like that the two triangles are equal or something, then it's just a general four sided shape.

Answer 12

If you look up the def of a rhombus, then it says *A rhombus is a parallelogram with equal side*

Answer 13

Answer 14

A rhombus with right angles is called a square!

Answer 15

so the figure is a rhombus?

Answer 16

As far as I know, yes, it is :P

Answer 17

It's a rhombus if the four outside lengths are the same and the triangles are the same. If only the triangles are the same but the four outside lengths are different, then it's a parallelogram.

Answer 18

if a = b then it's a rhombus, and a parallelogram otherwise. If the angle x is 90 degrees then it's a rectangle (and a square if also a = b).
