1. The Pythagorean Theorem
The square of the hypotenuse is equal to the sum of the squares of the two other sides:
a2+b2=c2 c a b

2. Remember that the area of a square is d2
What is the area of this figure? d

3. Cut out the right triangles and the square and see if you can arrange them to be a square of area c2.

4. Now rearrange them so that they form a region of area a2+b2
What does this tell you?????

5. From section 4.1 in your text: Work in your group on mindscapes 1-6 then 13-16. Finally, work on 22.

6. Homework:
Section 4.1 mindscapes 7-12 and 18 and Assume that the pizzas are perfect circles and remember that the area of a circle is
A = Ar2.
Write a reflection on your experience with the Pythagorean Theorem.
