Symmetries and Their Properties – Lessons from NCTM Illuminations
Ready-to-use online lessons that use interactive Java applets on symmetries:
Rotational symmetry, reflections, translations, and glide reflections.

Transformations
Use these interactive figures to explore geometric transformations (rotations, translations, and reflections AND a composition of these).
standards.nctm.org/document/eexamples/chap6/6.4/index.htm

Interactive Transformations
Each applet has interactive questions on the side panel so it acts as a great tutorial into rotations, reflections, translations, enlargements and combinations of these.
