Topics Covered in Types Of Quadrilateral


A Quadrilateral in which opposite sides are parallel is called a parallelogram. In the figure, ABCD is a parallelogram.  Here, AB || CD and AD || BC. Also, opposite sides of a parallelogram are equal.


A parallelogram, each of whose angle is 900, is called a rectangle. In the figure, PQRS is a rectangle.  We write it as rect. PQRS.


A Rectangle having all sides equal is called a square.  In the figure, LMNO is a square.


A parallelogram having all sides equal is called a rhombus. In the figure, PQRS is a rhombus.


A Quadrilateral in which two opposite sides are parallel and two opposite sides are non-parallel, is called a trapezium. In the figure, BCDE is a trapezium.
Point to Remember- If the two non-parallel sides of a trapezium are equal, then it is called an isosceles trapezium.


A Quadrilateral in which two pairs of adjacent sides are equal is known as kite.  PQRS is a kite such that PQ = QR and PS = RS.

Points to Remember- 
a) A square, rectangle and rhombus are all parallelograms.
b) A square is a Rectan...Read More
