Vertical angles are formed by intersecting lines. AEC and DEB are vertical angles. AED and CEB are also vertical angles.
Use points A, B, C, and D to change the angle values.
1. How are vertical angles different than linear pair angles?
2. Make a conjecture about the angle measures of a pair of vertical angles.
3. Are there any other types of angles in the diagram above? If so, what types of angles are there?
