उत्तर
Steps of Construction:

(i) Draw a line AB = 5 cm.
(ii)B as a center draw an angle with the help of compass ∠B = 60°. Cut the line with an arc BC = 6 4 cm.
(iii) Join AC.
(iv) Now, from A and B cut the bisector of ∠A and ∠B, which intersect each other at point D.
(v) With D as a centre draw an in a circle which touches all the three sides of AABC.
