This example demonstrates the relationships between angles formed when parallel lines are cut by a transversal. Key mathematical concepts include corresponding angles, alternate interior angles, and same-side interior angles. Using GeoGebra commands such as Segment, Line, Point, and Angle, dynamic relationships between these angles can be shown. Suitable for middle school and above students learning geometry.
