In mathematics, a locus (Latin for place, plural loci) is a collection of points which share a property. The term 'locus' is usually used of a condition which defines a continuous figure or figures, that is, a curve. An ellipse is the locus of points, the sum of the distances from which to the foci is a given value. * A hyperbola is the locus of points, the difference of the distances from which to the foci is a given value.
