AC9M9SP01 – recognise the constancy of the sine, cosine and tangent ratios for a given angle in right-angled triangles using properties of similarity
AC9M9SP02 – apply the enlargement transformation to shapes and objects using dynamic geometry software as appropriate; identify and explain aspects that remain the same and those that change
AC9M9SP03 – design, test and refine algorithms involving a sequence of steps and decisions based on geometric constructions and theorems; discuss and evaluate refinements
