Question

construct a triangle ABC in which BC 6cm,angleB 30° and AB-AC 3.5cm.justify your construction?​

Answer 1

1.take a line BC=6cm.

2.cut an arc of angle 30°on line BC from point B.

3. draw a line AB measuring3.5cm from point B.

4.draw another line whose measure is also 3.5cm from point C at an angle of 30° join it to A.

the ABC is our required triangle

justification:-

since AB=AC. Hence angleB=angleC= 30°

hence proved...
