उत्तर
Steps of Construction:
(i) Draw a line segment BC = 6 cm
(ii) With centres B and C and radius 6 cm, draw two arcs intersecting each other at A.
(iii) Join AB and AC
∆ ABC is the required equilateral triangle,
(iv) Draw the angle bisectors of ∠A, ∠B, and ∠C.
These are the lines of symmetry which are three in numbers as the triangle is equilateral.
