Before talking about the species of quadrilaterals, let united state recall what a quadrilateral is. A quadrilateral is a polygon which has the adhering to properties

4 vertices and also 4 political parties enclosing 4 angles.The sum of all interior angles that a quadrilateral is 360 degrees.We can additionally derive the sum of inner angle native the formula the polygon i.e. (n -2) × 180, where n is equal to the variety of sides of the polygon

A quadrilateral, in general, has actually sides of different lengths and angles of various measures. However, squares, rectangles, etc. Space special varieties of quadrilateral with several of their sides and angles being equal. This is the reason that the area of quadrilateral relies on which type of quadrilateral it is. In this article, us will comment on the special varieties of quadrilaterals and also their straightforward properties.

Different species of Quadrilaterals

There space six an easy types the quadrilaterals. Lock are:



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



It is a quadrilateral with two bag of parallel sides. The opposite sides are parallel and also equal in length. The contrary angles are equal in measure. In the parallelogram, ABCD, side abdominal is parallel to next CD and side ad is parallel to next BC.Also, the 2 diagonals formed to intersect each other at the midpoints. Together in the figure given below, E is the suggest where both the diagonals meet. SoLength AE = EC, & size BE = ED



It is a quadrilateral through all the 4 angles of equal measure, that is, every of lock is 90°. Both the pairs of opposite sides are parallel and also equal in length.



It is a quadrilateral through all the four sides having equal lengths. The Opposite political parties of a rhombus are parallel and also opposite angles room equal.



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



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


Some points about quadrilaterals to be retained in mental are:

Square, rectangle, and rhombus are types of parallelograms.A square is a rectangle and 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.
