Question: What is the relationship between the angles in a triangle (or quadrilateral)?

1. Gather data by measuring several different triangles (or quadrilaterals).[br]2. Record your data in a table. [br]3. Look for patterns in the angle measures.[br]4. When you think you have found a pattern, this is your hypothesis. Write it down. [br]5. Test your hypothesis by measuring a few more shapes. If you can wreck your hypothesis, go back to steps 1-3. If you can't wreck your hypothesis, move to step 6. [br]6. Share your hypothesis with your group. See if they can wreck it. If they can, go back to steps 1-3. If they can't, move to step 7. [br]7. Share your hypothesis with the class. See if we can wreck it. If we can, go back to steps 1-3. If we can't, move to step 8. [br][br]8. Congratulations!! You're awesome and you discovered a rule.
