12.6 Special Types of Quadrilaterals
How, we shall discuss about some special types of quadrilaterals, such as parallelogram, rectangle squ
hombus, trapezium and kite etc. with their properties.
Parallelogram : A quadrilateral in which both pairs of its opposite
des are parallel and equal is known as a parallelogram. In fig. ABCD is a
adrilateral in which -
Dosite sides AB // DC, and AB =DC
posite sides AD // BC, and AD = BC
A
ce it is a parallelogram.
