This example demonstrates dilation with a center. Key mathematical concepts include similarity transformation, polygons, and geometric construction. Using GeoGebra commands such as Polygon, Segment, and Intersect, a similar figure with a center can be constructed. Suitable for students at the junior high school level and above.

GeoGebra Commands & Parameters

  1. Polygon(Dilate[A, e, E], Dilate[B, e, E], Dilate[C, e, E], Dilate[D, e, E]) → poly1, a, b, c, d
  2. Segment(B, A) → f
  3. Segment(D, A) → g
  4. Segment(D, C) → h
  5. Segment(B, C) → i
  6. Intersect(d, a) → A'
  7. Intersect(c, d) → D'
  8. Intersect(c, b) → C'
  9. Intersect(a, b) → B'
