Questions about diagonals in squares and rectanges HELP :)

praet i wud like to corret here.
The Diagonals are equal in length for both square and rectangle..The only thing different is the length of side.
This may not be true. Have u seen a "kite"... in india people fly a lot of it.
A kite is a quadrilateral that can have its diagonals equal and perpendicular to each other at the same time and still its neither a square/rectangle. Or to look at it simply just draw to lines perpendicular to each other and of equal length. Now one line can be moved vertically along the length of another line and at each instance a quad, can be formed by joining the 4 end points of these four lines. Do u see what i am saying...?
Whereas, if all the angles of a quadrilateral are 90 degress it must be a square or a rectangle. And then if it is given that both diagonals are equal. Still i can only say that it must be either square/rectangle (coz both have equal diagonals)
correct me if i am wrong.

Thank you Vicky and Prat! I will find the question and then repost it!
THANKS AGAIN GUYS!!!!

Do you think the question asks something like following:

Is the equadrilateral square?

1) Both diagonals are of the same length.
2) All angles are 90 degrees.


If it does then;
The answer would be E, because we're not told anything about the length of the sides. Since that's the only thing makes such rectangle a square.

THank you for all of your help! I am still looking for the question and I can't seem to find it anywhere!

Hi frnd,

Both the statements are insufficient to answer the question. We need smthng on length to answer this question

guys,
r the diagnols of a rhombus equal and perpendicular to each other?

Rhombus is defined as a quadrilateral with 4 equal sides. So it could be either square or a parallelogram with 4 equal sides. If it is Square, the diagonls will be EQUAL, BISECT and aso PERPENDICULAR to each other.

If it is NOT square, the then the diagonals will be UNEQUAL, NON-PERPENDICULAR and will BISECT each other (I am not sure about the bisect part. Can somebody confirm?)

Vicky,

You made a good observation. Thanks for the post.
