In this lesson, we will learn what is meant by enlargement and how to enlarge shapes by an integer scale factor. It would be helpful if you could have squared paper and a ruler for this lesson.

In this lesson, we will learn how to enlarge shapes by a non-integer scale factor. It would be helpful if you could have squared paper and a ruler for this lesson.

In this lesson, we will learn how to enlarge a shape from a given point. It would be helpful if you could have squared paper and a ruler for this lesson.

In this lesson, we will learn how to enlarge a shape by a negative scale factor. It would be helpful if you could have squared paper and a ruler for this lesson.

In this lesson, we will learn how to describe an enlargement using the terms centre of enlargement and scale factor.

In this lesson, we will learn to define similarity and apply your understanding to similar triangles. We will also draw an enlargement.

In this lesson, we will apply your understanding of similarity to nested triangles to calculate missing sides and angles.

In this lesson, we will identify similar shapes and subsequently work out areas of similar shapes using our knowledge of scale factors.
