Steps of Construction
(i) Draw a ray AX with initial point A.
(ii) Taking A as centre and radius equal to length of side of the triangle draw an arc intersecting the ray AX at B.
(iii) Taking B as centre and the same radius draw an arc intersecting the arc drawn in step (ii) at C.
(iv) Join AC and BC to obtain the required triangle.
Arcs AB, AC and BC are of the same radii
Since, AB = BC = CA
