Before talking around the varieties of quadrilaterals, let united state recall what a quadrilateral is. A square is a polygon which has actually the adhering to properties

4 vertices and also 4 sides enclosing 4 angles.The amount of all inner angles the a square is 360 degrees.We can additionally derive the amount of inner angle native the formula the polygon i.e. (n -2) × 180, where n is same to the variety of sides of the polygon

A quadrilateral, in general, has sides of different lengths and also angles of various measures. However, squares, rectangles, etc. Are special species of quadrilateral with several of their sides and angles being equal. This is the factor that the area that quadrilateral counts on which type of quadrilateral it is. In this article, us will discuss the special types of quadrilaterals and their simple properties.

Different types of Quadrilaterals

There room six basic types of quadrilaterals. Castle are:

TrapeziumParallelogramRectangleRhombusSquareKite

Trapezium

It is a quadrilateral v one pair of the contrary parallel sides. In the trapezium, ABCD, side abdominal muscle is parallel to side CD.

*

Parallelogram

It is a quadrilateral with two pairs of parallel sides. The opposite sides room parallel and equal in length. The opposite angles are equal in measure. In the parallelogram, ABCD, side abdominal muscle is parallel to next CD and side advertisement 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 suggest where both the diagonals meet. SoLength AE = EC, & size BE = ED

*

Rectangle

It is a quadrilateral v all the 4 angles of equal measure, the is, every of lock is 90°. Both the bag of opposite sides space parallel and equal in length.

*

Rhombus

It is a quadrilateral v all the 4 sides having equal lengths. The Opposite political parties of a rhombus are parallel and also opposite angles space equal.

*

Square

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

*

Kite

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

*

Some points about quadrilaterals to be retained in mental are:

Square, rectangle, and also rhombus are types of parallelograms.A square is a rectangle as well as a rhombus.Rectangle and also rhombus space not a square.A parallelogram is a trapezium.A trapezium is not a parallelogram.Kite is not a parallelogram.
