This example demonstrates how to construct a rectangle using GeoGebra. Key mathematical concepts include geometric construction, segments, circles, and polygons. Commands such as Point, Segment, OrthogonalLine, Circle, Intersect, and Polygon are used to build the rectangle. Suitable for middle school and above students learning geometric construction.

GeoGebra Commands & Parameters

  1. Point(Circle[A, a]) → B
  2. Segment(A, B) → c
  3. OrthogonalLine(B, c) → d
  4. Circle(B, b) → e
  5. Intersect(e, d) → D, D_1
  6. Circle(A, b) → f
  7. OrthogonalLine(A, c) → g
  8. Intersect(f, g) → E, F
  9. OrthogonalLine(D_1, d) → h
  10. OrthogonalLine(D, d) → i
  11. Polygon(A, B, D, E) → poly1, a_1, b_1, c_1, e_1
