Parallelogram Pars with P Q = 4o5cmOR=3cm and apQR = Goo |
|
Answer» Step-by-step explanation: ⇒ We know that OPPOSITE sides and angle of parallelogram are equal. ⇒ And adjacent angles of parallelogram are SUPPLEMENTARY. By using these properties we are GOING to CONSTRUCT a parallelogram. ⇒ 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 |
