TrigonometryCoordinate GeometryGeometric Construction
This example demonstrates how to identify basic trigonometric functions from right triangles in different orientations. It involves core math concepts like trigonometric functions, right triangles, and coordinate geometry. Construction highlights include commands like Line, OrthogonalLine, Intersect, Segment, Angle, and If from GeoGebra. Suitable for high school students learning trigonometric functions and geometric constructions.

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
