Use the enlargement transformation to explain similarity and develop the conditions for triangles to be similar (ACMMG220) * understanding that similarity and congruence help describe relationships between geometrical shapes and form the basis of reasoning and proof * using the enlargement transformation to establish similarity * 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)
