In a parallelogram PQRS
PQ = 4.5 cm, QR = 3 cm, ZPQR = 60°.
= RS = 4.5cm PS = 3cm
[: Opposite sides of a parallelogram are equal]
Construction Steps:
1. Draw a line segment \(\overline{SR}\) with radius 4.5 cm.
2. With the centre Q draw a ray and an arc equal to 60° and 3 cm.
3. The intersecting point of these two keep as R’.
4. With the centres R, P draw arcs with 4.5 cm, 3 cm respectively. Keep ‘S’ as the intersecting point of these two arcs.
5. Join P, S and R, S.
6. ∴ The required parallelogram PQRS is formed.
