Question

7.
Construct a quadrilateral PQRS in which PQ = 7.5 cm,
QR=8 cm, ZP=80°, ZQ=70° and ZR=110°.​

Answer 1

⇒ Draw a line segment QR = 4.5cm.

⇒ Construct an angles of 110

∘

and 80

∘

at points Q and R.

⇒ Cut off PQ = 3.5cm and RS = 4cm.

⇒ Join PS.

⇒ Measure angle at point P.

⇒ We get ∠P=78
