FAMILY OF QUADRILATERALS

QUADRILATERAL ORIGIN

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 must be congruent and it must satisfy 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.

Hi, I am

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

KITE , 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.
