This example demonstrates how to construct parallelograms in the coordinate plane. Key mathematical concepts include properties of parallelograms, vectors, and translation transformations. Using GeoGebra commands such as PointIn, Polygon, and Segment, students can understand the construction process of parallelograms. Suitable for middle school and above students learning geometric construction.

GeoGebra Commands & Parameters

  1. PointIn(e) → A
  2. PointIn(e) → B
  3. PointIn(e) → C
  4. PointIn(e) → D
  5. Polygon(A, B, C, D) → q1, a_1, b_1, c_1, d_1
  6. Segment(A, B) → f
  7. Segment(B, C) → g
  8. Segment(C, D) → h
  9. Segment(D, A) → i
  10. Mode(l1) → l2
  11. Length(l2) → k
