Description
Locus of a point is a completely interactive lesson designed for GCSE learners.
In this lesson, learners will learn how to find the locus of points e.g.

the locus of points equidistant to two given points

Construct the midpoint and perpendicular bisector of a line segment;

the perpendicular from a point on a line;

the bisector of an angle;

a region bounded by a circle and an intersecting line;

a path equidistant from 2 points or 2 line segments, etc.
Teachers can use the lesson for wholeclass teaching. Learners can also use it at home for practice and revisions.
Lots of drag and drop activities as well as interactive worksheets with instant feedback.
A printable 3page worksheet is also included in this pack.
