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

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

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

Different species of Quadrilaterals

There are six basic types of quadrilaterals. Lock are:



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



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



It is a quadrilateral through all the 4 sides having equal lengths. The Opposite political parties of a rhombus are parallel and opposite angles room equal.



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



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


Some points around quadrilaterals to be kept in mental are:

Square, rectangle, and also rhombus are varieties 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 not a parallelogram.Kite is no a parallelogram.
