# Definition of Locus

A **locus** is the set of all points that share a given property, or, in other words, the path traced out by a moving point that satisfies certain conditions.

A locus is usually either a curve or a surface.

For example, a parabola is the locus of a point that moves so that its distance from a fixed point, called the focus is equal to its distance from a fixed line, called the directrix.
