Altitudes of a Triangle
2018-11-09 14:17
This GeoGebra applet demonstrates the geometric construction of the altitudes of a triangle. By drawing a triangle and the perpendicular lines from each vertex to the opposite side, it visually illustrates the intersection of the three altitudes (the orthocenter) and related geometric properties. It is suitable for middle or high school plane geometry teaching, helping students understand the defi
