CircleTrigonometryCoordinate GeometryGeometric Construction
This example demonstrates the geometric properties and trigonometric relationships of the unit circle. It involves core concepts like the circle, trigonometric functions, and coordinate geometry. Construction highlights include using GeoGebra commands such as Circle, Point, Segment, Polygon, Angle, and Intersect. Suitable for high school mathematics education to understand the definition and geometric meaning of trigonometric functions.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → B
  2. Circle(B, 1) → c
  3. Point(c) → C
  4. Segment(C, D) → f
  5. Segment(C, E) → g
  6. Segment(C, B) → h
  7. Polygon(D, C, B) → poly1, i, j, k
  8. Intersect(c, xAxis, 2) → A
  9. Angle(A, B, C) → α
