This example demonstrates the transformation rules of a shape after undergoing a dilation (scaling). Core math concepts include similarity transformation, scale factor, polygon construction, and coordinate geometry. It uses commands like Polygon, Dilate, and Segment in GeoGebra. Suitable for high school students learning geometric transformations and solid geometry.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a, b, c, d
  2. Dilate(D, e, E) → D'_1
  3. Dilate(A, e, E) → A'_2
  4. Dilate(B, e, E) → B'_2
  5. Dilate(C, e, E) → C'_2
  6. Segment(B'_2, C'_2) → b'
  7. Segment(A'_2, D'_1) → f
  8. Segment(D'_1, C'_2) → g
  9. Segment(A'_2, B'_2) → h
