Question

construct an isosceles triangle ABC in which angle A= 120 degree and AB = AC =5.5 cm

Answer 1

Answer:

We need to construct triangle ABC, in which vertical angle A = 120°. & equal sides AB = AC = 5.5 cm

STEPS: 1: construct AB = 5.5 cm

2: On AB, construct 120° angle XAB at A.

3: Now taking A as centre, with 5.5 cm radius draw an arc , intersecting AX at C.

4: Join B & C.

Triangle ABC is the required triangle
