Transformations and congruence

In this unit, students learn to understand and use the terms ‘reflection’, ‘rotation’ and ‘translation’, recognising what determines each type of transformation. They learn to understand and use the terms ‘transformation’ and ‘rigid transformation'. They identify and describe translations, rotations and reflections, as well as sequences of these.
