This example demonstrates the orthocenter of a triangle and related questions. The orthocenter is the point where the three altitudes of a triangle intersect. This example involves trigonometric functions, polygons, and geometric construction. Using GeoGebra commands such as Segment, OrthogonalLine, and Intersect, the construction of a triangle and its orthocenter is illustrated. Suitable for high school mathematics education and learning.
