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.
