TriangleTransformationGeometric Construction
This example demonstrates the similarity transformation of triangles. Key mathematical concepts include similar triangles and similarity transformations. Using GeoGebra commands such as Dilate (scaling) and Polygon (polygon), the properties of similar triangles can be visually demonstrated. Suitable for middle school and above students to learn geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Dilate(A, Scale, D) → A'
  3. Dilate(B, Scale, D) → B'
  4. Dilate(C, Scale, D) → C'
  5. Polygon(A', B', C') → poly1', c', a', b'
  6. Line(A, A') → f
  7. Line(B, B') → g
  8. Line(B, C) → h
  9. Line(C, C') → i
