Pythagorean Theorem

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore applets that simulate squaring the sides of a right triangle and practice putting the theorem to use. More advanced levels of the app use sides length of decimal numbers, requiring learners to deal with precision in their answer.
