Explore Parallel Lines and Transversal Angles

This example demonstrates the angle relationships formed when parallel lines are intersected by a transversal, focusing on alternate interior, corresponding, and consecutive interior angles. Key mathematical concepts include properties of parallel lines, angle congruence and supplementary relationships, and triangle angle sum. The construction uses GeoGebra commands like Point, Line, Intersect, and Angle measurement. Suitable for middle school and high school students to understand parallel line geometry and angle properties, or for teaching demonstrations.
