CircleVectorCoordinate GeometryTransformation
This example demonstrates the transformation of a circle under dilation, involving core math concepts like dilation, similarity transformation, vectors, and coordinate geometry. It uses GeoGebra commands like Locus and Vector. Suitable for high school students learning geometric transformations and similar figures.

GeoGebra Commands & Parameters

  1. Locus(P, t) → loc1
  2. Vector(C, P) → u
  3. Locus(P', t) → loc2
  4. Vector(C, A) → w
  5. Vector(P, P') → a
  6. Vector(A, A') → b
  7. Vector(A, P) → c
  8. Vector(A', P') → d
