AngleTrigonometryGeometric Construction
This example demonstrates the concept of trigonometric ratios, including sine, cosine, and tangent. Using GeoGebra commands such as Line, OrthogonalLine, Angle, and Polygon, the example visually explains the definition of trigonometric ratios and their changes at different angles. Suitable for students at the junior high school level and above to learn about trigonometric functions.

GeoGebra Commands & Parameters

  1. Line(A, B) → h
  2. OrthogonalLine(A, h) → i
  3. Angle(h, i) → α
  4. Point(i) → C
  5. Angle(C, B, A) → β
  6. Polygon(C, B, A) → poly1, Hypotenuse, Adjecent, Opposite
  7. Name(Adjecent) → A1
  8. Name(Hypotenuse) → B1
  9. Name(Opposite) → C1
  10. Angle(A, C, B) → γ
