Solution

The correct option is C Using a different radius, draw an arc on the first arc centered at the intersection point of the ray and the first arc.
The correct procedure for drawing an equilateral triangle is as follows:

Pick a point and draw a straight ray.

Draw an arc of any radius intersecting the ray, centered at the starting point of the ray.

Using the same radius, draw an arc on the first arc centered at the intersection point of the ray and the first arc.

Join the initial point of the ray with the intersection point of the two arcs.

Now, join the intersection points of the two arcs with the intersection of ray and the first arc.
