Quadrilateral family

Family of Quadrilaterals

A quadrilateral is a four sided polygon. Therefore the total number of degrees of interior angles is 360°

A rectangle is a parallelogram with four right angles. A rectangle is a parallelogram. Its opposite sides are congruent.It satisfies all other properties of parallelograms .

A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent. There are several formulas for the rhombus that have

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.

Adjacent sides equal

Adjacent sides equal and angles are 90 0

Angles are 900

SquareA square has the properties of a rhombus and a rectangle. Its sides intersect at 90° and all four sides are congruent.

KiteI am a special member of Quadrilateral family.

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.
