Answer:

A quadrilateral is a polygon which has the following properties

4 vertices and 4 sides enclosing 4 angles.

The sum of all interior angles of a quadrilateral is 360 degrees.

We can also derive the sum of interior angle from the formula of polygon i.e. (n -2) × 180, where n is equal to the number of sides of the polygon

A quadrilateral, in general, has sides of different lengths and angles of different measures. However, squares, rectangles, etc. are special types of quadrilaterals with some of their sides and angles being equal. This is the reason that the area of quadrilateral depends on which type of quadrilateral it is. In this article, we will discuss the special types of quadrilaterals and their basic properties.

Different Types of Quadrilaterals

There are six basic types of quadrilaterals. They are:

Trapezium

Parallelogram

Rectangle

Rhombus

Square

Kite

Trapezium

It is a quadrilateral with one pair of opposite parallel sides. In the trapezium, ABCD, side AB is parallel to side CD.

Parallelogram

It is a quadrilateral with two pairs of parallel sides. The opposite sides are parallel and equal in length. The opposite angles are equal in measure. In the parallelogram, ABCD, side AB is parallel to side CD and side AD is parallel to side BC.

Also, the two diagonals formed to intersect each other at the midpoints. As in the figure given below, E is the point where both the diagonals meet. So

Length AE = EC, & Length BE = ED

Rectangle

It is a quadrilateral with all the 4 angles of equal measure, that is, each of them is 90°. Both the pairs of opposite sides are parallel and equal in length.

Rhombus

It is a quadrilateral with all the four sides having equal lengths. The Opposite sides of a rhombus are parallel and opposite angles are equal.

Square

It is a quadrilateral in which all the sides and angles are equal. Every angle is a right angle (i.e. 90° each). The pairs of opposite sides are parallel to each other.

Kite

It is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.

Some points about quadrilaterals to be kept in mind are:

Square, rectangle, and rhombus are types of parallelograms.

A square is a rectangle as well as a rhombus.

Rectangle and rhombus are not a square.

A parallelogram is a trapezium.

A trapezium is not a parallelogram.

Kite is not a parallelogram.

Types of quadrilateral: Square, Rhombus, Rectangle, Parallelogram and Trapezoid.

Step-by-step explanation:

  • Quadrilaterals are two-dimensional shapes with closed structure by four straight lines or sides.
  • Quadrilaterals have fours sides and four vertices.
  • Sum of all the four angles in a quadrilateral is 360^{o}.

There are four types of quadrilaterals:

Square

  • A square has 4 sides equal in length.
  • All the four angles in a square are 90^{o}.
  • Opposite sides are parallel to each other.

Rectangle

  • A rectangle has 4 sides with all the four angles equal to 90^{o}.
  • Opposite sides are parallel and equal in length to each other.

Rhombus

  • Opposite angle are equal to each other.
  • Opposite sides are parallel to each.
  • All the sides of a rhombus are equal in length.

Parallelogram

  • Opposite angle are equal to each other.
  • Opposite sides are parallel to each.
  • Opposite sides are equal to each other.

Trapezoid

  • One pair of Opposite sides are parallel to each other.
