Step-by-step explanation:

Definition:

A quadrilateral is a simple closed figure with four sides.

Types of quadrilaterals

There are five types of quadrilaterals.

Parallelogram

Rectangle

Square

Rhombus

Trapezium

One common property of all quadrilaterals is that the sum of all their angles equals 360°.

Let us look into the properties of different quadrilaterals.

Parallelogram

Parallelogram Properties

Properties of a parallelogram

Opposite sides are parallel and congruent.

Opposite angles are congruent.

Adjacent angles are supplementary.

Diagonals bisect each other and each diagonal divides the parallelogram into two congruent triangles.

If one of the angles of a parallelogram is a right angle then all other angles are right and it becomes a rectangle.

Important formulas of parallelograms

Area = L * H

Perimeter = 2(L+B)

Rectangles

Rectangle Properties

Properties of a Rectangle

Opposite sides are parallel and congruent.

All angles are right.

The diagonals are congruent and bisect each other (divide each other equally).

Opposite angles formed at the point where diagonals meet are congruent.

A rectangle is a special type of parallelogram whose angles are right.

Important formulas for rectangles

If the length is L and breadth is B, then

Length of the diagonal of a rectangle = √(L2 + B2)

Area = L * B

Perimeter = 2(L+B)

Squares

Squares Properties

Properties of a square

All sides and angles are congruent.

Opposite sides are parallel to each other.

The diagonals are congruent.

The diagonals are perpendicular to and bisect each other.

A square is a special type of parallelogram whose all angles and sides are equal.

Also, a parallelogram becomes a square when the diagonals are equal and right bisectors of each other.

Important formulas for Squares

If ‘L’ is the length of the side of a square then length of the diagonal = L √2.

Area = L2.

Perimeter = 4L

Rhombus

Rhombus Properties

Properties of a Rhombus

All sides are congruent.

Opposite angles are congruent.

The diagonals are perpendicular to and bisect each other.

Adjacent angles are supplementary (For eg., ∠A + ∠B = 180°).

A rhombus is a parallelogram whose diagonals are perpendicular to each other.

Important formulas for a Rhombus

If a and b are the lengths of the diagonals of a rhombus,

Area = (a* b) / 2

Perimeter = 4L

Trapezium

Trapezium Properties

Properties of a Trapezium

The bases of the trapezium are parallel to each other (MN ⫽ OP).

No sides, angles and diagonals are congruent.

Important Formulas for a Trapezium

Area = (1/2) h (L+L2)

Perimeter = L + L1 + L2 + L3
