Answer:
Steps of Construction:
i) Draw a line segment BC = 4.5 cm ii) With B as centre and radius 6 cm and C as centre and radius 5 cm, draw arcs which intersect each other at A. iii) Join AB and AC.
ABC is the required triangle.
Draw the angle bisector of _BAC
Draw lines parallel to AB and AC at a distance of 2 cm, which intersect each other and AD at O.
With centre O and radius 2 cm, draw a circle which touches AB and AC.
