CircleTrigonometryGeometric ConstructionGraphing
This example demonstrates the relationship between angles, coordinates, and trigonometric values on the unit circle. It involves core concepts like the unit circle, trigonometric ratios, and geometric constructions. The construction uses GeoGebra commands such as Point, LineBisector, Intersect, and Segment. It is suitable for high school mathematics education to help students visually understand the definition and geometric properties of trigonometric functions.

GeoGebra Commands & Parameters

  1. Point(c) → A
  2. Point(c) → B
  3. Point(c) → C
  4. LineBisector(A, B) → f
  5. LineBisector(B, C) → g
  6. Intersect(f, g) → D
  7. Segment(F, D) → h
  8. Segment(H, I) → j
  9. Point(k) → J
  10. Point(k) → K
  11. Segment(J, K) → l
  12. Segment(D, G) → m
  13. Segment(D, N) → p
  14. Segment(D, L) → q
  15. Segment(D, M) → r
