PolygonTransformationGeometric Construction
This example demonstrates how to create similar figures through dilation transformations. Key math concepts include dilation, similar figures, and geometric transformations. It uses GeoGebra commands Polygon and Dilate to construct original and dilated polygons. Suitable for middle school and above students learning geometric transformations and properties of similar figures.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a, b, c, d
  2. Dilate(A, 0.5, E) → A'
  3. Dilate(B, 0.5, E) → B'
  4. Dilate(C, 0.5, E) → C'
  5. Dilate(D, 0.5, E) → D'
  6. Polygon(A', B', C', D') → poly1', a', b', c', d'
