** Using WeBWorK **

There are some trigonometry in my post re: Features and Development; you may like some of that. Go to the latest post there. ie Sketch_examples...

http://webwork.maa.org/moodle/mod/forum/discuss.php?d=3588

Also I am attaching Triangle.pg
This was written prior to "Sketch.pl" and I have posted it before.

The big thing I don't like about it is that the right triangle do not have the little square in the corner; this would have been easy had I had "Sketch".

"Triangle.pg" is actually many triangle problems. The intention is that you would make several versions (copies) and specify which kinds of triangles you want to deal with in each version.

I tried to be exhaustive and maybe I was; I gave up worrying about it when I realized I had way more than I would ever be able to use.

Any testing would have been done in very small settings; large chunks of "Triangle.pg" have possibly not been tested at all.
