This example demonstrates the generation of conic sections through two rotating angles. Key mathematical concepts include properties of conic sections and trigonometric functions. It uses Circle, Point, Line, Intersect, Rotate, Angle, and Locus commands in GeoGebra. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Circle(C1, 2) → c
  2. Point(c) → K
  3. Line(C1, K) → a
  4. Intersect(a, yAxis) → P
  5. Line(C2, P) → b
  6. Rotate(b, β, C2) → b'
  7. Rotate(a, α, C1) → a'
  8. Angle(a, a') → α_1
  9. Angle(b, b') → β_1
  10. Intersect(a', b') → A
  11. Locus(A, K) → loc1

AI Drawing Prompt Reference

Draw a circle C1 and select a point K on it. Construct a tangent line a at K, and let a intersect the y-axis at P. Draw a line b through P, then rotate b around C2 to get b', and rotate a around C1 to get a'. Calculate the angle β_1 between b' and b, and the angle α_1 between a and a'. Find the intersection A of a' and b', and trace the locus of A with K as the parameter to generate a hyperbola.
