TriangleCoordinate GeometryGeometric Construction
This example demonstrates how to construct the orthocenter of a triangle in GeoGebra by drawing the intersection points of the three altitudes. Key math concepts include perpendicular lines, intersection points, and triangle geometry. Construction involves commands like Polygon, OrthogonalLine, and Intersect to create the triangle, draw altitudes, and find the intersection. Suitable for high school students learning about orthocenters and geometric constructions.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. OrthogonalLine(A, a) → f
  3. OrthogonalLine(C, c) → g
  4. OrthogonalLine(B, b) → h
  5. Intersect(f, g) → Orthocenter

AI Drawing Prompt Reference

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