Geometric Construction of the Orthocenter
Loading the math board and drawing, please wait…
This GeoGebra example demonstrates the orthocenter of a triangle, which is the point where the three altitudes of a triangle intersect. Using the Polygon and OrthogonalLine commands, any triangle can be constructed and its orthocenter found. The example involves the geometric properties of triangles and vector concepts. Suitable for high school mathematics education and learning.
