This example demonstrates the concept of dilations, observing how the perimeter and area of a shape change. Key mathematical concepts include dilations, perimeter, and area. It uses GeoGebra commands such as Polygon, Dilate, and Perimeter. Suitable for middle school and above students to learn about the effects of dilations on the perimeter and area of shapes.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → q1, a, b, c, d
  2. Dilate(A, 2, E) → A'
  3. Dilate(B, 2, E) → B'
  4. Dilate(C, 2, E) → C'
  5. Dilate(D, 2, E) → D'
  6. Polygon(A', B', C', D') → q1', a', b', c', d'
  7. Perimeter(q1) → perimeterq1
  8. PointIn(q1) → Pointq1_1
  9. Perimeter(q1') → perimeterq1'
  10. PointIn(q1') → Pointq1'_1
  11. PointIn(q1') → Pointq1'
  12. PointIn(q1) → Pointq1
