PolygonCoordinate GeometryTransformation
This example demonstrates the transformation of polygons through rotation, involving core math concepts like rotation, coordinate geometry, and polygon properties. It uses GeoGebra commands such as Polygon, Intersect, and Rotate. Suitable for high school geometry transformation teaching and student exploration of geometric properties.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a, b, c, d
  2. Intersect(xAxis, yAxis) → E
  3. Rotate(A, 90°, E) → A'
  4. Rotate(B, 90°, E) → B'
  5. Rotate(C, 90°, E) → C'
  6. Rotate(D, 90°, E) → D'
  7. Polygon(A', B', C', D') → poly1', a', b', c', d'
  8. Rotate(A, (-(90°)), E) → A'_1
  9. Rotate(B, (-(90°)), E) → B'_1
  10. Rotate(C, (-(90°)), E) → C'_1
  11. Rotate(D, (-(90°)), E) → D'_1
  12. Polygon(A'_1, B'_1, C'_1, D'_1) → poly1'_1, a'_1, b'_1, c'_1, d'_1
  13. Rotate(A, 180°, E) → A'_2
  14. Rotate(B, 180°, E) → B'_2
  15. Rotate(C, 180°, E) → C'_2
  16. Rotate(D, 180°, E) → D'_2
  17. Polygon(A'_2, B'_2, C'_2, D'_2) → poly1'_2, a'_2, b'_2, c'_2, d'_2
  18. Rotate(A, 270°, E) → A'_3
  19. Rotate(B, 270°, E) → B'_3
  20. Rotate(C, 270°, E) → C'_3

  22. Polygon(A'_3, B'_3, C'_3, D'_3) → poly1'_3, a'_3, b'_3, c'_3, d'_3
  23. Rotate(A, (-(270°)), E) → A'_4
  24. Rotate(B, (-(270°)), E) → B'_4
  25. Rotate(C, (-(270°)), E) → C'_4
  26. Rotate(D, (-(270°)), E) → D'_4
  27. Polygon(A'_4, B'_4, C'_4, D'_4) → poly1'_4, a'_4, b'_4, c'_4, d'_4
