Altitude Definition

This example demonstrates the definition and construction of an altitude in a triangle. It involves core mathematical concepts such as triangles, line segments, perpendicular lines, and intersection points. The construction uses GeoGebra commands like Line, Point, Segment, OrthogonalLine, Intersect, and Angle to draw vertices, edges, altitudes, and feet of perpendiculars. Suitable for middle school and above students learning geometric constructions and triangle properties.
