In this lesson, we shall explore the concept of symmetry. As symmetries are always discussed with respect to certain transformations, we must first talk about transformations of the plane. We are going to focus on a special class of transformations, called isometries.

1. Transformations of the plane

2. Affine transformations

3. Isometries

4. Translation symmetry

5. Rotation symmetry

6. Reflection symmetry

7. Point symmetry
