THE PYTHAGOREAN THEOREM
Lesson title: Activities connected with the Pythagorean Theorem
Subject and Grade Level: 9 - 12th grade Mathematics
Brief Description: The investigation of selected activities connected with the theorem, which serves as the basis of the distance between two points.
Objectives —The students will be able to:
1. Recognize the importance of the Pythagorean theorem to find the length of a line segment.
2. Read written presentations of mathematics with understanding.
3. Understand the concept of Pythagorean Triples.
4. Demonstrate proofs of the theorem other than a Euclidean proof.
Educational/Skills Goals (Include academic (standards) and Internet goals)
1. Represent situations that involve variable quantities with expressions and equations.
2. Ask clarifying and extending questions related to mathematics they have read or heard about.
3. Appreciate the power of mathematical abstraction and symbolism.
4. Be able to conduct research (locate, analyze, conclude)

At the Proofs site find three proofs of the theorem. Include President Garfield's proof.
Draw diagrams showing the development of each proof. Indicate the lengths by means of variables.
Write a paper of at least 300 words about Pythagoras and his society.
Prepare an oral report, or a written paper, on "How the Pythagorean Theorem affected the ancient world and our world today".
Write a computer or graphing calculator program to generate a list of Pythagorean Triples for values up to 100
