Summary
● Parallelogram is a four sided closed shape in
which opposite sides are both parallel and equal.
● Area of the Parallelogram = b × h
sq. units, where b = base ; h = height.
● In a parallelogram if all the sides are equal
then it is called Rhombus.
● Area of rhombus = 1/2 × d1 ×
d2 sq. units, where d1, d2
are the diagonals.
● A parallelogram with one pair of non-parallel
sides is known as a Trapezium.
● Area of Trapezium = 1/2 × h(a+b) sq. units
● If the non - parallel sides of a Trapezium
are equal then it is known as an isosceles Trapezium.
