1. Demonstrate the Pythagorean Theorem - From NOVA
2. Interactive Proof of Pythagoras' theorem - This Java applet was written by Jim Morey. It won grand prize in Sun Microsystem's Java programming contest in the Summer of 1995.
3. Proof of the theorem - Demonstrated through a Quicktime animation.
4. Pythagorean Explorer - Students find the length of a side of a right triangle by using the Pythagorean Theorem, and then check their answers.
5. Pythagorean Theorem - Five question multiple-choice quiz from Glencoe Math
6. Pythagorean Theorem - Its many proofs (43 to be precise)
7. Pythagorean Theorem - Nineteen applets
8. Pythagorean Theorem - Discover how the Pythagorean Formula describes the relationships between the lengths of the legs and hypotenuse of a right triangle. Work through the lesson, experiment with the interactive figure and then answer five questions. [caution: do not submit until you have selected answers to all of the questions]
9. Pythagorean Theorem - Animated Proof of the Pythagorean Theorem
10. Pythagorean theorem and right triangle facts - Given the length of three sides, determine if a right triangle is being described [8 questions]
11. Pythagorean Theorem: 1 - A java applet that allows students to investigate this theorem.
12. Pythagorean Theorem: 2 - A java applet that allows students to investigate this theorem.
13. Solving a right triangle - This example illustrates how finding the height of the pyramid is equivalent to solving the right triangle. The virtual reality media can help students visualize the interrelation between the 3-dimensional pyramid and the 2-dimensional right triangle.
14. Squaring the Triangle - Students learn about how the Pythagorean Theorem works, through investigating the standard geometric proof. Parameters: Sizes of the legs of the triangle.
15. Squaring the Triangle - Learn about how the Pythagorean Theorem works, through investigating the standard geometric proof. Parameters: Sizes of the legs of the triangle.
16. The Pythagorean Theorem, Distance Formula and Intro to Trigonometry - Practice activities
17. Using the Pythagorean Theorem - Once you know the equation a2 + b2 = c2 is true, then you can use it to solve all kinds of problems. Try the Pythagorean theorem with two other examples given on this page. Internet4classrooms is a collaborative effort by Susan Brooks and Bill Byles.
