ICSE Class 10 Mathematics Revision Notes Chapter 16 - Loci

What is a Locus?

A locus is a set of points, in geometry, which satisfies a given condition or situation for a shape or a figure. The plural of the locus is termed loci. The area of the loci is called the region. The word locus is derived from the word location. 


What is the meaning of Locus?

When it comes to Maths a locus is a curve or other shape made by all the points satisfying a particular equation of the relation between the coordinates, or by a point, line, or moving surface. All the shapes such as circle, ellipse, parabola, hyperbola, etc. are defined by the locus as a set of points.


In real-life you must have heard about the word ‘location’.  Did you know? In actuality, the word location is derived from the word locus itself. Locus defines the position of something. When an object is situated somewhere, or something happened at a place, it is described by locus. For example, the area has become a locus of opposition to the government.


What is Locus of Points?

The locus of points defines a shape in geometry. Suppose, a circle is the locus of all the points which are equidistant from the centre. Similarly, the other shapes such as an ellipse, parabola, hyperbola, etc. are defined by the locus of the points.


The locus is only for curved shapes. However, it is said that these shapes can be regular or irregular. Locus is not for the shapes having vertex or angles inside them.


What is the Locus of a Circle?

The set of all points which form geometrical shapes such as a line segment, a line,  circle, a curve, etc., and whose location satisfies the conditions is the locus. So, we can say, instead of seeing them as a set of points, they can be seen as places where the point can be located or moved.


Concerning the locus of the points or loci, the definition goes as follows. It is the circle that is described as the set of all points equidistant from a fixed point, where the fixed point is the centre of the circle and the distance of the sets of points from the centre is the radius of the circle. Let us say, P is the centre of the circle and r is the radius of the circle, i.e. the distance from point P to the set of all points or the locus of the points.
