PolygonTransformationGeometric Construction
This example demonstrates the dynamic process of polygon transformation through dilation (scaling, rotation). It involves core math concepts: dilation, polygons, transformation, geometric construction. Construction highlights include using GeoGebra commands like Polygon, Dilate, Segment, Rotate. Suitable for high school mathematics teaching to understand transformation geometry and graph properties.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a_1, b_1, c, d
  2. Dilate(B, Angle, E) → B'
  3. Dilate(C, Angle, E) → C'
  4. Dilate(D, Angle, E) → D'
  5. Segment(E, A_p) → a
  6. Segment(A_p, A) → g
  7. Dilate(A_p, Angle, E) → G
  8. Dilate(A, Angle, E) → A'
  9. Segment(G, A') → g'
  10. Polygon(A', B', C', D') → poly2, a'_1, b', c', d'
  11. Rotate(E, ((-Angle) * 3.141592653589793 / 180), E) → E'
  12. Dilate(A_p, Angle, E) → H
  13. Segment(E', H) → a'
  14. Dilate(A_p, Angle, E) → F
