TriangleAngleGeometric Construction
In collections Geogebra Investigations
This example demonstrates the properties of the orthocenter of a triangle. Key mathematical concepts include the orthocenter, angles, and straight lines. Using GeoGebra commands such as Polygon, Segment, and Angle, the construction of a triangle and its orthocenter is illustrated. Suitable for high school geometry education.
