TriangleTrigonometryGeometric Construction
This example demonstrates the properties of the altitudes and the orthocenter of a triangle. Key math concepts include altitudes, orthocenter, similarity transformation, and trigonometric functions. It is constructed using GeoGebra commands like Polygon, OrthogonalLine, and Intersect. Suitable for university-level mathematics courses or for geometry enthusiasts.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. OrthogonalLine(A, a) → d
  3. OrthogonalLine(C, c) → e
  4. OrthogonalLine(B, b) → f
  5. Intersect(d, e) → D
