Question

construct triangle ABC whose BC = 7cm, angle B= 60 degree and ab +ac =13cm

Answer 1

Answer:

hence, the∆ abc is formed

Step-by-step explanation:

solution :-

step of construction

1. draw a line BC with 7 cm and ∆B as 75° and let the lay be bx.
2. measure the compass with larger ab+ac = 13 cm and from point B as centre,cut an arc on ray bx. let the are interest bx at∆ and join cd.
3. now, we will draw a perpendicular bisector of CD.
4. mark point A where the perpendicular bisector intersects bd and then join AC.
5. hence, the∆ ABC is formed.
