Edited version of a program originally written by Andrew G. Bennet at Kansas State University. I never heard of PHP until I ran across this program at JOMA (Journal of Online Mathematics and its Applications). It inspired me to dedicate the summer of 2003 to learning PHP and working on my triangles program.
I have created a SCORM version of this program written with Flash™. Contact me if you are interested in purchasing a license to use the SCORM compliant version.
