Construct an equilateral triangle ABC with side 6 cm. Draw a circle circumscribing the triangle ABC.
Construct an equilateral triangle ABC with side 6 cm. Draw a circle circumscribing the triangle ABC.

Steps for construction:

i) Draw a line segment BC = 6 cm

ii) Draw two arcs of radius 6 cm with centres B and C, which intersect each other at A.

iii) Then, join AC and AB.

iv) Draw perpendicular bisectors of AC, AB and BC intersecting each other at O.

v) Draw a circle with centre O, and radius OA or OB or OC which will pass through A, B and C.

=> this is the required circumcircle of triangle ABC.
