I'm not getting any good sense of what you know. And the core of your question has nothing to do with Python: it's more an elementary algebra/geometry homework assignment. Frankly speaking, for the kind of geometry questions you've asked so far, I believe you should already know how do that. You haven't said anything about what you've tried, or what difficulties you're running into. As far as I can tell, you haven't put in any effort into anything except for repeating a problem statement. See: http://www.catb.org/~esr/faqs/smart-questions.html#homework We're not going to do your homework. Show us what you're really having trouble with, and if it's programming related, we will try to help point things out. But other than that, you really have to do your own work. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
