TriangleVectorCoordinate GeometryGeometric Construction
This example demonstrates geometric constructions and properties based on numerical SSA (Side-Side-Angle) criteria. It involves core math concepts like congruence, number operations (LCM/GCD), orthocenter, hyperbola, standard deviation, and 2D vectors. Construction highlights include using commands like Segment, OrthogonalLine, Point, Ray, Polygon, Angle, and Midpoint. Suitable for high school and above learners for understanding geometric constructions and applications.
