Let's assume side of equilateral triangle is 5 cm.
Steps of construction :
1) Draw a line segment AB of length 5 cm.
2) Taking 5 cm as radius, and A as centre, draw an arc.
3) Taking 5 cm as radius, and B as centre, draw another arc.
4) Let C be the point where the two arcs intersect . Join AC and BC and label the sides.
Thus, △ ABC is the required equilateral triangle.
Justification :
By construction, AB = AC = BC (Radius of equal arcs)
Since, all sides are equal , therefore, △ ABC is an equilateral triangle
Note: Take 5 cm in Image
