You may want to see my FREE website for additional explanation on the Theorem of Pythagoras.  The easiest way to find the website is to use the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com.  Near the bottom of this page is a link that takes you to my Homepage.  


On my Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time."  Choose "Basic Algebra" and look in "Chapter 2" for the "Section 2.10 Theorem of Pythagoras," or in "Intermediate Algebra" in Chapter 4.  I think you will really like the "Math in Living Color" pages that go with these sections.
