Types of Symmetry Leading to Groups

http://www.learner.org/courses/mathilluminated/units/6/textbook/02.php

I found this website on symmetry today and I thought that others in our class may appreciate it. I’ve looked it over and it all seems to be pretty legit, also it comes from a credible source: learner.org.

This site does a nice job of explaining symmetry, giving us examples of symmetry, and relating it back to topics which we have already learned such as equilateral triangles and circles. Maybe it’ll help since you will have a better point of reference for understanding the new material.
