Hi John,
I just started poking around. These look good and I may refer them to my students. One early quibble:

The incircle construction says:
"Place the compass at the incenter and adjust the radius to touch the circle."

I think if you are doing a classical construction, you need to construct the perpendicular first - since setting the compass to just touch the side is not a defined point. (It sure is tempting though.)
