TriangleCircleGeometric Construction
This example demonstrates the geometric properties and construction method of the orthocenter intersection in a triangle. Core math concepts include triangles, altitudes, angle bisectors, intersections, and circles. Construction involves commands like Polygon, Angle, LineBisector, Intersect, and Circle in GeoGebra. Suitable for high school geometry education and construction learning.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Angle(C, A, B) → α
  3. Angle(A, B, C) → γ
  4. Angle(B, C, A) → ε
  5. LineBisector(c) → f
  6. LineBisector(b) → g
  7. LineBisector(a) → h
  8. Intersect(f, g) → D
  9. Circle(D, A) → d
