1.  Turn in your 12.1/12.2 worksheet.  Take a 9.1/9.2 worksheet from the front.  Take your graphing calculator.  In your notebook, list the trigonometric ratios and what they mean.

3.  Understand the Pythagorean Theorem more deeply.  Prove the Pythagorean Theorem  Use the Pythagorean Theorem to solve for missing sides.  Use problem solving skills.

7.  A theorem is a conjecture that has been proved. A demonstration, like the one in the investigation, is the first step toward proving the PYTHAGOREAN THEOREM

8. 1. Find the area of the whole figure. 2. Find the area of individual parts and add them together. 3. Set your two areas equal to each other. (They represent the same area.) 4. Show that a 2 +b 2 =c 2.
