Demonstration of Triangle's Orthocenter by paige26998

This example demonstrates the geometric properties and construction method of a triangle's orthocenter. It involves core mathematical concepts such as perpendicular lines, intersection points, polygon construction, and coordinate geometry. The construction uses GeoGebra commands like Polygon, OrthogonalLine, and Intersect, along with objects A, B, C, t1, c, a, b, f, g, h, D. It is suitable for high school mathematics teaching and geometric construction learning, helping to understand special points of a triangle and their relationships.
