1. Draw two parallel lines L1 and L2 which have distance between 3 cm
2. Let point A on line L2
3. Make 60 degree angle at point A and we get point D on L1
4. draw a arc of radius of of 4 cm 5. let point C and make 60 degree angle at point C which is touch the arc at point F then parellelogram ABCD constructed.
