Loci

Objectives

• Locus from a fixed point

• Constructing a perpendicular bisector

• (to find the locus that is equidistant from two points)

• Locus from a line

• Constructing the bisector of an angle

• (to find the locus that is equidistant from two lines)

Locus from a fixed point

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

Constructing a Perpendicular Bisector

You can find the method by clicking on the image below:

Watch the video.

Constructing the perpendicular bisector helps you find the locus of points that are equidistant from two points.

Bisecting an angle

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