My book Geometry Labs is now available for free download on my Web site.
Whew! It was a bit of work to get it ready.

PS: In addition to the book itself, I’ll be adding links to revisions and extensions of the labs. So far, a revision of the rep-tile lab, and an extension of the soccer angles lab. I’m happy to post other people’s revisions and extensions there.
