This example illustrates the definition of a rectangle. Key mathematical concepts include angles and slope. Using GeoGebra commands such as Segment, OrthogonalLine, Point, Intersect, and Angle, a rectangle can be constructed. Suitable for middle school and above students to learn geometric construction.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. OrthogonalLine(B, f) → g
  3. OrthogonalLine(A, f) → h
  4. Point(h) → C
  5. OrthogonalLine(C, h) → i
  6. Segment(A, C) → j
  7. Intersect(g, i) → D
  8. Segment(B, D) → k
  9. Segment(D, C) → l
  10. Angle(C, A, B) → α
  11. Angle(A, B, D) → β
  12. Angle(B, D, C) → γ
  13. Angle(D, C, A) → δ
