No, the diagonals of a trapezium do not cross at right angles. In a trapezium, the diagonals intersect each other, but the angles formed at the point of intersection are not necessarily right angles. The angles formed by the diagonals depend on the specific measurements and properties of the trapezium.
yes 9
They are either kites or (if the diagonals bisect each other) rhombuses.
A right trapezium. A right trapezium. A right trapezium. A right trapezium.
yes it is A trapizium has no right angles therefore there are no perpendicular.* * * * *Nonsense! A trapezium can have two adjacent angles which are right angles.
A parallelogram
No
Yes they do. * * * * * Uh oh. No, they don't.
The diagonals of a rectangle do not cross at right angles
The diagonals of a square and a rhombus cross at right angles.
rectangle
No.
No.
No but they cross at right angles in a square
kite
Yes, they do.
No, not normally
yes, they do. though they are not always equal in length they always cross at right angles.
