Symmetry

1. Symmetry

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

3. Line of Symmetry These lines are not lines of symmetry.

4. Your Turn! Is the dotted line a line of symmetry? Yes

5. Your Turn! Is the dotted line a line of symmetry? Yes No

6. Your Turn! Is the dotted line a line of symmetry? Yes No

7. Your Turn! Is the dotted line a line of symmetry? Yes No

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

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

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

11. Your Turn! Does the figure have bilateral symmetry (at least one line of symmetry)? A Yes

12. Your Turn! Does the figure have bilateral symmetry (at least one line of symmetry)? 5 No

13. Your Turn! Does the figure have bilateral symmetry (at least one line of symmetry)? Yes

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

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