Looking at this page now was really exciting--it's come a very long way since Thursday.

My first question is why did you choose to have the summaries be a separate page? I'd really like to see that within the same page. It looks great, and quickly makes a lot of things clear.

Instead of saying "please see references at the bottom of the page" can you link to one or two of them in your sentence "to learn more about.... check out [link] or [link]."

*Well, I was thinking that I would have the summaries be a separate page in case, in the future, someone were to write a Elliptic Geometry page and wanted to link to it.*- Ryang1 (7/6)

I don't think you need "Without going into too much detail" at the beginning of that sentence. You can just start it after that.

Also, your example of finding the distance between two points is very confusing, and it feels like that formula comes out of nowhere.

I'd really suggest looking that this book McCleary, Geometry From A Differentiable Viewpoint, Cambridge University Press, 1997. This is the textbook for the intro geometry course (math 55).

One of my concerns about this page is that it doesn't properly define "line" in all contexts. It would be helpful to first state that lines are straight lines in Euclidean geometry, and great circles in the last case. That text book goes through those definitions clearly, and you might want to look at it as an example.

In one of the early chapters it goes over a lot of this stuff, and I think it might be helpful for you to read it over a bit.
