Question

Construct a triangle ABC in which base BC=4.5 cm, angle B= 60 degree and AB+AC=7.1 cm

Answer 1

Answer:

Justification:-

After drawing ΔDBC with BC=4.5cm, ∠B=45

o

and DB=8cm. The perpendicular bisector of DC is drawn and it intersects DB at A.

So, we get AC=AD

BD=8cm

⇒BA+AD=8cm

⇒AB+AC=8cm

Hence ΔABC is the required triangle.
