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?
