This example demonstrates the orthocenter of a right triangle, which is the point where the three altitudes of the triangle intersect. Using GeoGebra commands Polygon, OrthogonalLine, and Intersect, the construction of a right triangle and finding its orthocenter is illustrated. Suitable for middle school and above students to learn about triangle properties.
