CircleAngleVectorGeometric Construction
This example demonstrates the properties of chords in a circle. It involves key mathematical concepts such as circles, vectors, and angles. Using GeoGebra commands like Intersect, Point, Segment, Rotate, and Angle, dynamic chords and related angles can be constructed. Suitable for middle school and above students to learn geometric construction and circle properties.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → O
  2. Point(c) → B
  3. Segment(O, B) → f
  4. Rotate(B, θ°, O) → A
  5. Angle(B, O, A) → α
  6. Segment(O, A) → g
  7. Segment(A, B) → h
