UNIT

In this lesson we will be exploring drawing loci that are equidistant between two points

Introducing loci

In this lesson we will be looking at how to draw perpendicular bisectors on a coordinate grid.

Perpendicular bisectors

In this lesson we will be looking at drawing angle bisectors.

Angle bisectors

in this lesson we will be looking at different ways of finding triangle centres.

Triangle centres

In this lesson we will be practising how to use perpendicular and angle bisectors to find different regions.

Plan problems

In this lesson we will learn what is meant by congruent shapes and be able to identify shapes that are congruent.

Congruence

In this lesson, we will start learning the conditions that make triangles congruent.

Congruence and triangles (Part 1)

In this lesson, we will carry on learning about the conditions for which triangles are congruent.

Congruence and triangles (Part 2)
