Vertical Angles

Vertical angles are formed by intersecting lines. <AED and <CEB are vertical angles. <AEC and <DEB are vertical angles.
Use points A, B, C, and D to change the angle values. Make a conjecture about the angle measures of a pair of vertical angles.
Make a conjecture.
What is the relationship between the measures of vertical angles?
