A rhombus looks like this! Which one do you think would fit perfectly?|dw:1377200785148:dw|

OpenStudy (anonymous):

@AkashdeepDeb D?

OpenStudy (akashdeepdeb):

Not quite! All angles are not actually 90 right? It is just the diagonals bisecting each other

OpenStudy (akashdeepdeb):

So it should be?

OpenStudy (anonymous):

C correct?

OpenStudy (akashdeepdeb):

And why do you say that?

OpenStudy (anonymous):

i thought it was D because of the right angles in the middle

OpenStudy (akashdeepdeb):

But those aren't the Angles of the rhombus right?

OpenStudy (akashdeepdeb):

Why do you think C should be right? :)

OpenStudy (anonymous):

because the diagonals

OpenStudy (anonymous):

intersect

OpenStudy (akashdeepdeb):

AT?

OpenStudy (anonymous):

60

OpenStudy (akashdeepdeb):

Don't you think it'd be 90 from the diagram? See there is a difference between the angles of the rhombus and the diagonals intersection angle!

OpenStudy (akashdeepdeb):

The correct option then would be A because it DOES HAVE all sides congruent! B is INCORRECT because adjacent sides ARE equal! C is incorrect because diagonals intersect at 90' D is also incorrect because it can have any angle [EVEN 90'] :D Getting this now?
