This one could be used as almost an entire unit in itself. It starts out a
little slow; the moving acute/obtuse angle is a little boring. By the end
though, the applets are very impressive. I like that you can fix a, b, or c for
the triangle applet. I especially like the Pythagorean Theorem one  It's great
that the user can change the shape of the triangle that the applet uses, showing
that a^2 + b^2 always equals c^2. I'm very interested to see how the 'unit'
will end. (It says that it is still under construction.)
