When A locus of points equidistant to a central point?

A locus of points equidistant to a central point forms a geometric shape known as a circle. In a two-dimensional plane, every point on the circumference of the circle is the same distance from the center, which is the fixed point. This distance is referred to as the radius of the circle. The concept can also be extended to higher dimensions, such as spheres in three-dimensional space.
