This is an example for teacher demonstration on angle pairs. It illustrates concepts such as vertical angles, corresponding angles, and alternate interior angles. Using GeoGebra commands like Line, Intersect, Point, Ray, Angle, etc., these angle pairs can be constructed. Suitable for middle and high school mathematics education.
