Before talking about the species of quadrilaterals, let united state recall what a square 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 the a quadrilateral is 360 degrees.We can also derive the amount of inner angle from the formula that polygon i.e. (n -2) × 180, wherein n is equal to the number of sides of the polygon

A quadrilateral, in general, has actually sides of various lengths and angles of various measures. However, squares, rectangles, etc. Are special types of quadrilateral with several of their sides and angles being equal. This is the reason that the area that quadrilateral relies on which form of square it is. In this article, us will talk about the special varieties of quadrilaterals and their simple properties.

Different species of Quadrilaterals

There are six straightforward types that quadrilaterals. Castle are:



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



It is a quadrilateral v two pairs of parallel sides. The contrary sides room parallel and also equal in length. Opposing angles room equal in measure. In the parallelogram, ABCD, side ab is parallel to side CD and side ad is parallel to side BC.Also, the 2 diagonals formed to crossing each other at the midpoints. Together in the figure given below, E is the point where both the diagonals meet. SoLength AE = EC, & length BE = ED



It is a quadrilateral v all the 4 angles of equal measure, the is, every of them is 90°. Both the pairs of opposite sides room parallel and also equal in length.



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



It is a quadrilateral in which every the sides and angles space equal. Every angle is a best 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 sides are nearby to every other.


Some points around quadrilaterals come be retained in mental are:

Square, rectangle, and also rhombus are types of parallelograms.A square is a rectangle as well as a rhombus.Rectangle and rhombus are not a square.A parallel is a trapezium.A trapezium is not a parallelogram.Kite is not a parallelogram.
