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
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 similarityunderstanding that similarity and congruence help describe relationships between geometrical shapes and are important elements of reasoning and proof
