This example demonstrates the orthocenter of a triangle, which is the point where the three altitudes of a triangle intersect. Using GeoGebra commands Polygon, OrthogonalLine, and Intersect, we can construct a triangle and find its orthocenter. This example is suitable for middle and high school students to help them understand the geometric properties of triangles.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → t1, c, a, b
  2. OrthogonalLine(A, a) → f
  3. OrthogonalLine(B, b) → g
  4. OrthogonalLine(C, c) → h
  5. Intersect(f, g) → D

AI Drawing Prompt Reference

Draw an arbitrary triangle. From each vertex, construct a line perpendicular to the opposite side, creating three altitudes. These three altitudes intersect at a single point, known as the orthocenter. Clearly mark the orthocenter and keep the triangle, the three altitude lines, and the orthocenter visible to illustrate the geometric property.
