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.
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, four
Yes
The diagonals of a kite are perpendicular, and one diagonal is bisected. ~
No but they are both 4 sided quadrilaterals
