Answer
Steps of construction :
Draw a line segment BC = 4 cm.
With centers B and C, draw two arcs of radius 4 cm which intersect each other at A.
Join AB and AC. Hence, equilateral triangle ABC is formed.
Draw the perpendicular bisectors of AB and BC. Let these bisectors meet at the point O.
With O as center and radius equal to OA, draw a circle. The circle so drawn passes through the points A, B and C, and is the required circumcircle of △ABC.
