50 pages loaded with lesson plans, examples, and assessments. You only need to stroll to this topic.

Interactive Math Applets
This is a collection of 19 applets that demonstrate various applications of the Pythagorean theorem

Unit Circle
An applet is provided, showing a line passing through (-1, 0) and a point with integral coordinates. The point where the line intersects the unit circle is used to generate a right triangle, and subsequently a Pythagorean Triple is generated.
  

Pythagorean Triples

Discover a simple pattern for generating Pythagorean Triples.

Generate Pythagorean Triples
This site contains a java applet that generates Pythagorean triples and explains an algebraic algorithm for producing at least infinitely many of them.

Fermat's Last Theorem
An interview with Andrew Wiles who proved Fermat's Last Theorem.

Pythagorean Triple Relationships
This is very advanced, but I couldn't pass it up. Did you know that the products of Pythagorean triples is always divisible by 60? This site also explains the link between matrices and Pythagorean triples.

Pythagorean Demonstration
An animated demonstration of why the Pythagorean Theorem works.

Pythagorean Lessons
