Use the enlargement transformation to explain similarity and develop the conditions for triangles to be similar (ACMMG220)

- establishing the conditions for similarity of two triangles and comparing this to the conditions for congruence
- using the properties of similarity and ratio, and correct mathematical notation and language, to solve problems involving enlargement (for example, scale diagrams)
- using the enlargement transformation to establish similarity, understanding that similarity and congruence help describe relationships between geometrical shapes and are important elements of reasoning and proof
