This example demonstrates a timed quiz designed to help recognize basic trigonometric functions. Random triangles are drawn with two sides highlighted, and a red dashed line represents the third side. Key math concepts include trigonometric functions (sine, cosine, tangent), triangle geometry, and angle measurement. It uses commands and objects like Line, OrthogonalLine, Intersect, Segment, Angle, If, and Textfield in GeoGebra. Suitable for high school students for review and practice.

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. If(second < 10, "0", "") → textsec
  12. Textfield(name) → InputBox1
