Quadrilaterals are of six types.

They are geometric figures with four lateral sides (quad means four). Therefore any closed figure with four sides can be called a quadrilateral. The sides of the quadrilateral may be parallel or irregular, equal or unequal, based on which the different types of the quadrilateral are named. Squares and rectangles can be considered particular types of quadrilaterals, as some sides or angles are equal. Due to the differences in shapes, the areas of each quadrilateral may also stay different and this depends on the kind of quadrilateral. There are mainly 6 types of quadrilaterals. Each one of them has particular characteristics.

Basic Properties Of Quadrilaterals

• 4 vertices

• 4 sides

• 4 angles

• Sum of interior angles 360 degree

Different Types

1. Trapezium

2. Parallelogram

3. Rectangle

4. Rhombus

5. Square

6. Kite

Trapezium

• One pair of opposite sides are parallel

• Both the diagonals will be of different lengths

• Diagonals do not bisect at right triangles

• Opposite angles are not equal

Isosceles Trapezium

• A pair of opposite sides are parallel

• Non-parallel sides are of equal length

• Both of the diagonals are of equal length

• Adjacent angles are equal

Parallelogram

• Opposites are parallel and equal in length

• Angles opposite to each other will be equal

• Diagonals bisect each other

• Diagonalsdivides the parallelogram into 2 congruent triangles

Rectangle

• Opposite sides are Equal

• Opposite sides are parallel

• All angles are right angles

• Diagonals bisect each other

• Diagonals are of equal length

Rhombus

• All sides are equal

• The opposite sides are parallel

• Opposite angles are equal

• Diagonals bisect each other

• Diagonals bisect at right angles

Square

• All sides are equal

• The opposite sides are parallel

• All angles are 90°

• Diagonals bisect each other

• Diagonals bisect at right angles

• Diagonals are of equal length

Kite

• Two pairs of adjacent sides are equal

• Diagonals intersect at right angles
