Formerly a physicist, I am now an italian retired high school math teacher, with some experience in informatics. During the last fifteen years I produced software for my students for assessment and training via the Internet. From year 2003 the most vital part of my site is at www.polarprof.org/geometriagon where people find about 2000 problems on geometric constructions with compass and ruler interactively solvable in a web page.
