Question

construct a quadrilateral pqrs with PQ=4.3 CM, QR=3.5 CM, RS=4.5 CM, PS= 3 cm and angle Q=75° . don't use my points please gove appropriate answer otherwise I will delete that answer​

Answer 1

Answer:

⇒ 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

∘

.
