Vertical and Linearly Paired Angles
The applet below shows vertical and linearly paired angles.
Move the blue points to change the value of the angles. See how the value of each angle compares to the value of the other angles.
How are the measurements of the green angles related to the measurements of the purple angles?
How are the measurements of the green angles related to each other?
How are the measurements of the purple angles related to each other?
