Yes 2 of them
No, kites do not have congruent diagonals.
Most quadrilaterals will satisfy that requirement. Those that do (squares and kites) are the exception.
Diagonals are perpendicular to each other in several types of quadrilaterals, including rhombuses, squares, and kites. In a rhombus, the diagonals bisect each other at right angles, while in a square, they are both perpendicular and equal in length. Kites also have diagonals that intersect at right angles, though one diagonal is usually longer than the other.
Quadrilaterals with diagonals that are perpendicular to each other include rhombuses, squares, and kites. In a rhombus and a square, the diagonals bisect each other at right angles. In a kite, the diagonals intersect at right angles but do not necessarily bisect each other. These properties are characteristic of these specific types of quadrilaterals.
Yes, they do.
Every closed figure with at least 4 sides has at least 2 diagonals. Every quadrilateral (figure with exactly 4 sides) has exactly 2 diagonals. That includes all parallelograms, rhombera, rectangles, squares, trapezoids, diamonds, and kites, as well as all other irregular quadrilaterals.
They are either kites or (if the diagonals bisect each other) rhombuses.
Yes.
Yes
Yes
Yes, four
The diagonals of a kite are perpendicular, and one diagonal is bisected. ~
