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

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

A quadrilateral, in general, has actually sides of different lengths and angles of different measures. However, squares, rectangles, etc. Are special varieties of quadrilateral with few of their sides and angles being equal. This is the factor that the area of quadrilateral depends on which type of square it is. In this article, us will discuss the special varieties of quadrilaterals and also their basic properties.

Different types of Quadrilaterals

There room six basic types that quadrilaterals. They are:



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



It is a quadrilateral v two bag of parallel sides. The opposite sides space parallel and equal in length. Opposing angles room equal in measure. In the parallelogram, ABCD, side abdominal is parallel to next CD and also side advertisement is parallel to side BC.Also, the two diagonals created to intersect each various 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 with all the 4 angle of same measure, the is, each of them is 90°. Both the bag of the opposite sides space parallel and equal in length.



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



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



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


Some points about quadrilaterals to be preserved in mental are:

Square, rectangle, and rhombus are types 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.
