Interactive Practice:

Primary Resources: Reflection
Color the squares and reflect the given pattern in a line.

Primary Resources: Rotation
From the arrow you can change the shape. Use the circular arrow buttons to rotate the shapes either 90 or 45 degrees.

Symmetry Game
Tell how many lines of symmetry a shape has.

Online Kaleidoscope
Create your own kaleidoscope creation with this interactive tool.

Make Your Own Mandala
A mandala is a circular symmetrical design based on eights. Make your own and experiment with symmetry.

Similarity and Congruence
An interactive lesson with explanations and quiz from Absorb Mathematics course written by Kadie Armstrong, a mathematician.

National Library of Virtual Manipulatives for Interactive Mathematics: Geometry
Collection of interactive geometry activities: Congruent triangles, fractals, geoboard activities, Golden rectangle, Ladybug leaf, Ladybug mazes, platonic solids, tangrams, tessellations, transformations and more.

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.

Use these interactive figures to explore geometric transformations (rotations, translations, and reflections AND a composition of these).

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.
