Demonstration of Orthocenter and Midpoints Collinearity

This example demonstrates whether the orthocenter and the midpoints of the sides of a triangle are collinear in any arbitrary triangle. The core mathematical concepts involved include orthocenter, midpoint, collinearity, triangle geometry properties. The construction highlights commands like Segment, OrthogonalLine, Intersect, Midpoint, Line, AreCollinear, and Prove in GeoGebra. It is suitable for high school geometry learning to understand important triangle properties and geometric proof methods.
