Complementary, Supplementary, Angle around a Point

Observe: Use the slider to Rotate line CD. 1. Look for Vertical Angles, Linear Pairs and Adjacent Angles. 2. Look for a pair of Complementary Angles? What relationship exist between complementary angles? 3. Look for a pair of Supplementary Angles? What relationship exist between supplementary angles? 4. What is the sum of all of the angles around point O? Questions: Move the slider toward the Left (But not all the way to the left...) 5. Name one of each: an obtuse angle, acute angle, and right angle. 6. Are vertical angles? 7. Are adjacent angles? 8. Are complementary angles? 9. Are supplementary angles? 10. Find
