Expert Answer
Steps of Construction:
1. Draw BC = 7.5 cm and at B make an angle of 60° and produce its arm downwards.
2. Cut BD = 1.5 cm. Join DC.
3. Draw perpendicular bisector of DC to meet DB produced at A. Join AC.
4. ABC is the required triangle.
5. Bisect angle ACB and draw a line parallel to BC at a distance of 2 cm to cut the bisector of angle ACB at O.
6. With O as centre and radius 2 cm, draw the required circle.
