本范例动态展示了三角形的高，并提供了定义写作提示。通过使用GeoGebra命令，用户可以直观地理解三角形高的概念。构造摘要中的关键命令包括Polygon, Line, Segment, OrthogonalLine, Intersect, Dilate, Angle等。适合初中及以上学生或教师使用。

GeoGebra 命令及参数

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Line(A, B) → f
  3. Segment(A, C) → g
  4. Segment(C, B) → h
  5. OrthogonalLine(C, f) → i
  6. Intersect(f, i) → D
  7. Dilate(C, If[0 < d ≤ 1, 1 - d, 0], D) → C'
  8. Segment(C, C') → j
  9. Segment(C, D) → k
  10. Angle(C, C', A) → α
