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

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

A quadrilateral, in general, has actually sides of different lengths and angles of various measures. However, squares, rectangles, etc. Room special species of quadrilateral with several of their sides and also angles gift equal. This is the factor that the area of quadrilateral depends on which form of quadrilateral it is. In this article, we will comment on the special types of quadrilaterals and their basic properties.

Different species of Quadrilaterals

There are six straightforward types the quadrilaterals. Castle 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 contrary sides room parallel and equal in length. The opposite angles space equal in measure. In the parallelogram, ABCD, side ab is parallel to next CD and also side ad is parallel to side BC.Also, the 2 diagonals created to intersect each other at the midpoints. Together in the number given below, E is the allude where both the diagonals meet. SoLength AE = EC, & length BE = ED



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



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



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



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


Some points about quadrilaterals to be preserved in mental are:

Square, rectangle, and also rhombus are species of parallelograms.A square is a rectangle and a rhombus.Rectangle and also rhombus are not a square.A parallelogram is a trapezium.A trapezium is no a parallelogram.Kite is no a parallelogram.
