This example demonstrates the relationship and conversion between polar and rectangular coordinates, including graphical representation. Core math concepts involve polar coordinates, rectangular coordinates, trigonometric functions, and geometric constructions. It uses GeoGebra commands like OrthogonalLine, Intersect, Segment, Midpoint, Point, and Angle. Suitable for high school mathematics students learning coordinate systems and transformations.

GeoGebra Commands & Parameters

  1. OrthogonalLine(A, xAxis) → a
  2. Intersect(a, xAxis) → B
  3. Segment(A, B) → d
  4. Intersect(xAxis, yAxis) → C
  5. Segment(C, B) → c
  6. Segment(A, B) → b
  7. Midpoint(b) → D
  8. Midpoint(c) → E
  9. Point(xAxis) → F
  10. Angle(F, C, A) → θ
  11. Segment(A, C) → r
