Question

Draw a parallelogram PQRS, PQ = 5 cm, QR = 4 cm and ∠PQR = 120⁰​

Answer 1

Answer:

Draw a line segment PQ=5cm

⇒ Construct an angle of 70

∘

at point Q.

⇒ Cut off QR=4cm

⇒ Construct an angle of 110

∘

at point P.

⇒ Cut off PS=4cm

⇒ Join RS

⇒ Thus PQRS is a required parallelogram

⇒ Let a=5cm and b=4cm

⇒ Perimeter of parallelogram PQRS=2(a+b) =2(5+4)=18

⇒ The perimeter of parallelogram PQRS=18cm

solution
