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

Elaborations

• establishing the conditions for similarity of two triangles and comparing this to the conditions for congruence (Skills: Numeracy, Critical and Creative Thinking)
• using the properties of similarity and ratio, and correct mathematical notation and language, to solve problems involving enlargement (for example, scale diagrams) (Skills: Numeracy)
• 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 (Skills: Literacy, Numeracy)
