AngleGeometric Construction
This example demonstrates the geometric relationships between vertical angles and linear pairs. It involves core concepts like angle equality and supplementary angles. Constructed using GeoGebra commands such as Circle, Point, Line, Intersect, Segment, and Angle. Suitable for middle school geometry education to visually understand angle relationships.
