I took down most of my previous uploads. They were chapters of a course named "Common Core Geometry". I've become skeptical of the CC standards for geometry. High school students don't do well with the attempt to inject rigid transformation into proof. It's better, I think, to stick with the old method - a congruence postulate (perhaps SAS) and a similarity postulate (perhaps AA), and build your proofs with no mention of any transformation.
Here is the new class. I call it "Elementary Euclidean Geometry", because that's what it is. It's Euclidean in two senses. First, it's very like the geometry of Euclid's Elements. Euclid would recognize it immediately. Second, it has nothing to say about the so-called non-Euclidean geometries. The class, moreover, is elementary in the sense that it nowhere attempts to make use of any results from the calculus.
The focus is upon proof throughout. If you want a traditional geometry course in which students will have ample proof practice and will prove all major results, this is it.
The course is now free. Rework, republish - do with it as you please. I request only that you acknowledge its creator and that you not attempt to make a profit from my work or any work that grows out of it.
