Which parallelograms have congruent diagonals?
Only rectangles (squares included) have congruent diagonals, because all their angles are congruent (90 degrees). If you have angles larger or smaller than 90 degrees it makes the diagonals different lengths.
What are three attributes of a square?
The sides are equal The angle between adjacent sides is 90 degrees There are two diagonals The diagonals are equal in length The diagonals make 90 degrees with each other The diagonals make 45 degrees with the sides
Does a rectangle have perpendicular diagonals?
No, rectangles don't have any 'diagnal' on them! ha haatechnically yes they do but they are not perpandicular they will cross at a point but wont be 90 degrees because the sides are not equal lengthsNo
Does a rhombus have perpendicular diagonals?
Yes the perpendicular diagonals intersect at right angles or 90 degrees
What is a quadrilateral with unequal diagonals which meet at 90 degrees?
A kite.

Do the diagonals of a trapezium cross at 90 degrees?
No.
Can a rhombus have equal diagonals?
No but its diagonals bisect each other at 90 degrees
How many diagonals which are equal does a kite have?
None but the diagonals intersect at 90 degrees
Which other shape besides square and rhombus have diagonals that intersect at 90 degrees angles?
It is a kite that has diagonals that intersect each other at 90 degrees.
Why are not all parallelograms rectangles why?
Rectangles include 4 angles of 90 degrees each
Does a rhombus have perpendicular diagonals?
Yes the perpendicular diagonals intersect at right angles or 90 degrees
Are the diagonals of a rhombus congruent?
No, the diagonals of a rhombus are not congruent, but they do intersect each other at 90 degrees.
What is a quadrilateral with unequal diagonals which meet at 90 degrees?
A kite.
The diagonals of a kite are perpendicular and exactly one of them is?
90 degrees
