They are either kites or (if the diagonals bisect each other) rhombuses.
The diagonals of a square and a rhombus cross at right angles.
The diagonals of a rectangle do not cross at right angles
Yes, the diagonals of a kite do cross at 90 degrees. In a kite, one diagonal bisects the other, and the angles formed at the intersection are right angles. This property is a key characteristic of kites, distinguishing them from other quadrilaterals.
They are a square, a rhombus and a kite.

No.
No.
No but they cross at right angles in a square

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, they do. though they are not always equal in length they always cross at right angles.
