This example demonstrates the effects of negative enlargement and translation. Key mathematical concepts include geometric transformations, translation, and enlargement. Using GeoGebra commands such as Polygon, Translate, and Dilate, the example constructs shapes with negative enlargement and translation. Suitable for students at the junior high school level and above.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a, b, c, d
  2. Translate(A, (m, n)) → A'_1
  3. Translate(B, (m, n)) → B'_1
  4. Translate(C, (m, n)) → C'_1
  5. Translate(D, (m, n)) → D'_1
  6. Polygon(A'_1, B'_1, C'_1, D'_1) → poly1'_1, a'_1, b'_1, c'_1, d'_1
  7. Dilate(A, k, Centre) → A'
  8. Dilate(B, k, Centre) → B'
  9. Dilate(C, k, Centre) → C'
  10. Dilate(D, k, Centre) → D'
  11. Polygon(A', B', C', D') → poly1', a', b', c', d'
