TriangleCoordinate GeometryGeometric Construction
This example demonstrates the construction of the orthocenter of a triangle to understand its properties. Key mathematical concepts include the orthocenter, perpendicular lines, and intersection points. Using GeoGebra commands such as Polygon, OrthogonalLine, and Intersect, the geometric construction process of the orthocenter is visually illustrated. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Polygon(C, A, B) → poly1, b, c, a
  2. OrthogonalLine(A, a) → d
  3. OrthogonalLine(C, c) → e
  4. OrthogonalLine(B, b) → f
  5. Intersect(f, d) → Orthocenter
  6. Slope(e) → j
  7. Slope(d) → g
  8. Slope(f) → h

AI Drawing Prompt Reference

Draw a triangle ABC. Then, construct a perpendicular line from point A to side BC, a perpendicular line from point C to side AB, and a perpendicular line from point B to side AC. The intersection of these three perpendicular lines is the orthocenter of triangle ABC.
