This example demonstrates the concepts of sine and cosine ratios. By constructing triangles and using GeoGebra commands such as Segment and Distance, it visually illustrates the definitions and variations of sine and cosine at different angles. Suitable for middle school and above students learning trigonometry.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. Segment(B, C) → g
  3. Segment(C, A) → h
  4. Segment(K, D) → i
  5. Segment(L, E) → j
  6. Segment(M, F) → k
  7. Segment(N, G) → l
  8. Segment(O, H) → m
  9. Segment(P, I) → n
  10. Segment(Q, J) → p
  11. Distance(A, B) → AB
  12. Distance(A, Q) → AQ
  13. Distance(A, J) → AJ
  14. Distance(A, C) → AC

AI Drawing Prompt Reference

Draw a triangle ABC, then draw line segments from point A to B, C, Q, and J. These segments will help illustrate the concepts of sine and cosine. Finally, measure the lengths of AB, AQ, AJ, and AC.
