Orthocenter and Triangle Properties Demo

This example demonstrates the orthocenter of a triangle and its related properties. The core mathematical concepts involved include orthogonal lines, area calculation, arithmetic operations, rotation, and conic sections. The construction highlights the use of GeoGebra commands like Polygon, OrthogonalLine, Intersect, Segment, and Angle to build and showcase the geometric relationships. Suitable for high school mathematics education to understand triangle geometry and transformations.
