01 / QUICK RECAP
Connect the ideas.
- Translation: every point has the same horizontal and vertical movement.
- An x-axis reflection reverses y; a y-axis reflection reverses x.
- A rotation needs a centre, angle and direction.
- Apply a sequence to each successive image; order can matter.
- Rigid transformations preserve lengths, angles, perimeter and area. Reflection reverses vertex orientation.
