2. Line of Symmetry- a line on which a figure can be folded so that both sides match exactly.

3. These lines are not lines of symmetry.

4. Is the dotted line a line of symmetry?

5. Is the dotted line a line of symmetry?

8. Bilateral Symmetry- when a figure has at least one line of symmetry.

9. These figures do not do not have bilateral symmetry.

10. Does the figure have bilateral symmetry (at least one line of symmetry)?

11. Does the figure have bilateral symmetry (at least one line of symmetry)?

15. Rotational Symmetry- when a figure matches itself after being rotate 180º or less.

16. These figures do not have rotational symmetry, because when rotated, they are no longer an exact match.

17. Does the figure have rotational symmetry?

18. Does the figure have rotational symmetry?
