1. Symmetry
Objective:
To identify reflectional (line), rotational, and point symmetry using reflections and rotations.

2. Symmetry
Symmetry: a figure has symmetry if there is and isometry that maps the figure onto itself.
Reflectional symmetry (line symmetry): a type of symmetry for which there is a reflection that maps a figure onto itself. The reflection line is the line of symmetry. The line of symmetry divides a figure with reflectional symmetry into two congruent halves.

3. Symmetry
Rotational symmetry: the type of symmetry for which there is a rotation of or less that maps a figure onto itself.
Point symmetry: the type of symmetry for which there is a rotation of that maps a figure onto itself.
