A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent. Properties of the rhombus:
1. all four sides are congruent2. Diagonals bisects each other3. Diagonals are perpendicular
A square is a rhombus and a rectangle. In other words, if each angle of a rhombus is 90°, then it's a square.

Kite is a quadrilateral:
* has two pairs of sides.* each pair is adjacent sides (they meet) that are equal in length.
Also, the angles are equal where the pairs meet.
Diagonals meet at a right angle, and one of the diagonal bisects (cuts equally in half) the other.
