Most quadrilaterals do not.
Rhombus.
Square.
Most quadrilaterals will not have congruent diagonals: rectangles (incl squares) and isosceles trapezium are the exception.
i think its a trapezoid...
A quadrilateral in which adjacent angles are congruent is called a kite. In a kite, the adjacent angles formed by the intersecting diagonals are congruent. This property distinguishes a kite from other types of quadrilaterals, such as a parallelogram or a rhombus, where adjacent angles are not necessarily congruent. Kites have specific properties and characteristics that make them a unique type of quadrilateral in geometry.
No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).
A quadrilateral with four congruent sides and uncongruent diagonals is a Rhombus. See related link for a picture
The quadrilateral that must have diagonals that are congruent and perpendicular is the square. This is because its diagonals form a right angle at its center.

It is a square.
A rhombus
A square would fit the given description.
In a quadrilateral, the diagonals are only congruent for rectangles (or squares, which is a special kind of rectangle). Note: they are not congruent for a Rhombus.
