Locus from a fixed point

A locus means a path. 'Loci' is the plural of locus. It shows us the path or region that a point can travel according to certain rules. 

The locus of all points at a fixed distance from a line.Watch the video here.

The locus of all points that are equidistant from two lines: Bisecting an angle

We use this method to find the locus of all points that are equidistant from two lines.
