Definition 3.1
The path traced by a moving point under some specified geometrical condition is called its locus.
1. Equation of a locus
Any relation in x and y which is satisfied by every point on the locus is called the equation of the locus.

For example,
i. The locus of a point P ( x1, y1) whose distance from a fixed point C(h, k) is constant, is a circle. The fixed point ‘C’ is called the centre.
ii. The locus of a point whose distances from two points A and B are equal is the perpendicular bisector of the line segment AB.
