1. Warm-up Read page 462 to 464. Talk to a partner, can you explain what the pythagorean theorem is?
2. Use activestudio to show evidence that the pythagorean theorem is true. Put a grid on the screen and make a right triangle with two sides with measures 6 and 8 or 9 and 12 or 5 and 12. Then, construct squares on each side. Then rotate the diagram and see that a^2 + b^2 = c^2.
Look at this video when you are finished.
3. Classwork 1 though 11 page 465.
Homework 12 to 16. If you need to, write these problems down. Otherwise, I'll post them here.
12. A basball infield is a square, each side measuring 90 feet. To the nearest foot, what is the distance from home plate to second base?
13. The diagonal of a square measures 32 meters. What is the area of the square?
14. What is the length of the diagonal of a square whose area is 64 cm squared?
15. The length of the three sides of a right triangle are consecutive integers. Find them.
16. A rectangular garden 6 meters wide has a diagonal measureing 10 meters. Find the perimeter of the garden.
