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

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

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

Different species of Quadrilaterals

There room six simple types that quadrilaterals. Castle are:



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



It is a quadrilateral v two bag of parallel sides. Opposing sides are parallel and also equal in length. The contrary angles are equal in measure. In the parallelogram, ABCD, side ab is parallel to next CD and side advertisement is parallel to side BC.Also, the two diagonals formed to intersect each various other at the midpoints. Together in the number given below, E is the point where both the diagonals meet. SoLength AE = EC, & size BE = ED



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



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



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



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


Some points around quadrilaterals come be maintained in mind are:

Square, rectangle, and rhombus are varieties 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 no a parallelogram.Kite is no a parallelogram.
