Geometric Construction of the Orthocenter of a Triangle

2018-09-13 00:36
This applet demonstrates how to construct the orthocenter of a triangle in GeoGebra. Given vertices A, B, and C, orthogonal lines (altitudes) are drawn to each side using the OrthogonalLine command. The Intersect command finds the intersection of these altitudes, yielding the orthocenter D. This visually illustrates the geometric properties and construction of the orthocenter.
