FunctionTrigonometryGeometric Construction
This example dynamically illustrates the basic properties of sine, cosine, and tangent functions. It involves the concept of similar triangles and explores the values of these trigonometric functions by constructing angles and side lengths. GeoGebra commands used include Intersect, Point, Polygon, and Angle. Suitable for high school mathematics education and learning, particularly in the areas of trigonometry and geometric construction.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Point(xAxis) → B
  3. Point(yAxis) → C
  4. Polygon(A, B, C) → t1, c, a, b
  5. Angle(C, B, A) → α
  6. Angle(A, C, B) → β
  7. Angle(B, A, C) → γ
