Helpful sites - Currently 1 for Geometry

So I'm going to be helping someone out with geometry and algebra, so throughout the semester I may be posting sites and such here.

Math Open Reference - not the fanciest website around, but I found it gave great instructions on how to use a compass and a straight edge to draw angles, and it had java animations that actually showed the motions that go into it (a plus in my book). I haven't explored it fully, but it looks like it's mostly geometry and some calculator help. Hope this is useful!
