This example demonstrates the animation of constructing a circle using a pin, string, and pen. It involves core math concepts like circle, vectors, logarithmic functions, addition, ellipse, and Pythagorean theorem. The construction uses GeoGebra commands and objects such as Point, Segment, Circle, and Angle. Suitable for middle school and above students learning geometric constructions.

GeoGebra Commands & Parameters

  1. Point(Circle[A, a]) → B
  2. Segment(A, B) → b
  3. Circle(A, B) → c
  4. Point(c) → B'
  5. Angle(B, A, B') → β
  6. Segment(A, B') → e
  7. Circle(A, a) → f
