Before talking about the varieties of quadrilaterals, let us recall what a quadrilateral is. A square is a polygon which has the following properties

4 vertices and 4 political parties enclosing 4 angles.The amount of all internal angles that a quadrilateral is 360 degrees.We can also derive the sum of inner angle indigenous the formula the polygon i.e. (n -2) × 180, wherein n is same to the number of sides that the polygon

A quadrilateral, in general, has sides of various lengths and also angles of different measures. However, squares, rectangles, etc. Are special species of quadrilaterals with few of their sides and also angles gift equal. This is the reason that the area that quadrilateral relies on which form of quadrilateral it is. In this article, we will talk about the special types of quadrilaterals and their an easy properties.

Different types of Quadrilaterals

There space six basic types the quadrilaterals. They are:



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



It is a quadrilateral with two bag of parallel sides. The opposite sides room parallel and also equal in length. Opposing angles are equal in measure. In the parallelogram, ABCD, side abdominal muscle is parallel to next CD and side advertisement is parallel to next BC.Also, the two diagonals created 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, the is, each of lock is 90°. Both the pairs of the opposite sides space parallel and also equal in length.



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



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



It is a square that has 2 bag of equal-length sides and these sides are nearby to every other.


Some points about quadrilaterals to be preserved in mental are:

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