apply the enlargement transformation to shapes and objects using dynamic geometry software as appropriate; identify and explain, using language of similarity, ratio and scale, aspects that remain the same and those that change
Elaborations
comparing the ratio of lengths of corresponding sides of similar triangles and angles
using the properties of similarity to solve problems involving enlargement
investigating and generalising patterns in length, angle, area and volume when side lengths of shapes and objects are enlarged or dilated by whole and rational numbers; for example, comparing an enlargement of a square and a cube of side length 2 units by a factor of 3 increases the area of the square, (3×2)2=9×22=9 times the original area and the volume of the cube, 23, to (3×2)3=27×23=27 times the volume
