Question

Construct a triangle using the given data: AB - AC = 1.2 cm, BC = 6.0 cm and ∠B = 60°

Sum

Solution

AB - AC = 1.2 cm, BC = 6.0 cm and ∠B = 60°

Steps of Construction:
1. Draw a line segment BC = 6 cm.
2. With B as centre, draw ∠TBC = 60°.
3. From BT, cut BS = 1.2 cm.
4. Join S and C.
5. Draw perpendicular bisector of SC which cut BT at A.
6. Join AC.
Thus, ABC is the required triangle.
