Reflective Symmetry

Definition A pattern that occurs when two halves of a whole are each others mirror images. This is also called Bilateral Symmetry.

Examples Imagining a mirror placed between the left and right halves of the images reveals reflective symmetry.

Activities Follow the next three slides to three different web links.

Reflection Codes This website explores reflective symmetry using a mirror. It uses numbers and letters to illustrate how symmetric symmetry can be used to make secret codes. After exploring this website see if you can use a secret code.

Reflection Interactive Applet This website offers an interactive example of reflective symmetry. With this virtual manipulative you can create objects with pattern block pieces and explore Reflections as transformations of the plane.

Inversions This website explores the inversion artist, Scott Kims works. An inversion is a word or name written so it reads in more than one way. This type of art is heavily based on reflective symmetry. After exploring this website, make an inversion of your own.
