This example demonstrates the concept of cone angles. Key mathematical concepts include angles and cones. Using GeoGebra commands such as Intersect, Angle, and Rotate, the intersection points and angles of a cone can be constructed. Suitable for high school geometry education.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Segment(C, B) → f
  3. Segment(C, D) → g
  4. Segment(D, B) → h
  5. Angle(B, C, D) → α_1
  6. Rotate(B, (360° * cos(α)), D) → B'
  7. Angle(B, D, B') → β
  8. Segment(D, B') → i
  9. Rotate(B, (360° * cos(α) / 2), D) → B'_1
  10. Angle(B, D, B'_1) → γ
  11. CircumcircleSector(B, B'_1, B') → d
  12. PointIn(d) → Pisted
  13. Segment(A, D) → j
