उत्तर
Steps of construction:
- Draw a line segment BC = 5.6 cm
- With centers B and C, draw two arcs of 5.6 cm radius each which intersect each other at A.
- Join AB and AC.
- Draw angle bisectors of ∠B and ∠C intersecting each other at O.
- From O, draw OL ⊥ BC.
- Now with centre O and radius OL, draw a circle which will touch the sides of ΔABC.
This is the required circle.
