FunctionTrigonometryGeometric Construction
This example demonstrates the recognition of trigonometric functions through randomly drawn triangles with highlighted sides. It involves core concepts like sine, cosine, tangent, angle measurement, and triangle geometry. Constructed using GeoGebra commands such as Line, OrthogonalLine, Intersect, Segment, Angle, Textfield, and If, it is suitable for high school mathematics teaching, providing instant practice and visualization of trigonometric functions.

GeoGebra Commands & Parameters

  1. Line(A, B) → a
  2. OrthogonalLine(C, a) → b
  3. Intersect(a, b) → D
  4. Segment(D, C) → d
  5. Segment(C, A) → e
  6. Segment(D, A) → f
  7. Angle(D, A, C) → α
  8. Angle(C, A, D) → β
  9. Angle(C, D, A) → γ
  10. Angle(A, D, C) → δ
  11. Textfield(name) → InputBox1
  12. If(second < 10, "0", "") → textsec

AI Drawing Prompt Reference

Draw a triangle ABC with AB as the base and C as the vertex. From point C, draw a perpendicular line to AB, intersecting at point D. Connect CD, CA, and DA to form angles α, β, and γ. In the input box, enter the degree of angle α, and if the angle is less than 10 degrees, add a '0' before the number.
