AngleTrigonometryGeometric Construction
This example demonstrates the relationships between sine, cosine, and tangent in trigonometry. By constructing a triangle, it shows the relationship between angles and sides. GeoGebra commands used include Ray, Point, Segment, OrthogonalLine, Polygon, Angle, etc. Suitable for high school mathematics education and learning trigonometric concepts.

GeoGebra Commands & Parameters

  1. Ray(B, B_1) → a_1
  2. Point(a_1) → A
  3. Segment(A, B) → c
  4. OrthogonalLine(B, c) → c_2
  5. Point(c_2) → D
  6. Ray(B, D) → d
  7. Point(d) → C
  8. Polygon(C, A, B) → poly1, b, e, a
  9. Angle(B, A, C) → α
  10. Angle(A, C, B) → β
  11. Angle(C, B, A) → γ
