This example demonstrates dilations when the center is not at the origin. Key mathematical concepts include similarity transformations and properties of triangles. It uses commands like Point, Polygon, and Dilate in GeoGebra. Suitable for middle school and above students to learn about similarity transformations and their applications.

GeoGebra Commands & Parameters

  1. Point(yAxis) → B
  2. Point(xAxis) → C
  3. Polygon(A, B, C) → poly1, c, a, b
  4. Dilate(A, 2, D) → A'
  5. Dilate(B, 2, D) → B'
  6. Dilate(C, 2, D) → C'
  7. Polygon(A', B', C') → poly1', c', a', b'
