उत्तर
Steps of Construction:
(i) Draw ∆ABC in which AB = 4.2 cm. BC = 6 cm. and AC = 5 cm.
(ii) Draw the perpendicular bisectors of any two sides of the triangle. Let these intersect at O.
(iii) Taking O as center and OA or OB or OC as radius draw a circle.
This circle will pass through vertices A, B and C.
