http://illuminations.nctm.org/index_o.aspx?id=139

The National Council of Teachers of Mathematics


This site is a tutorial about the mathematical properties of reflections. There are four lessons, which include describing reflections, relationships between reflections and symmetry (bilateral symmetry), reflections across two mirror lines, and the conclusion. Lessons include interactive applets and questions to enhance the concepts covered.
