This example demonstrates the concept of reflection transformation. It involves reflecting line segments and points. Using GeoGebra commands such as Polygon, Segment, Mirror, and Intersect, the reflected shapes can be constructed. Suitable for students at middle school level and above to learn about geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → q1, a, b, c, d
  2. Segment(E, F) → f
  3. Mirror(A, f) → A'
  4. Mirror(B, f) → B'
  5. Mirror(C, f) → C'
  6. Mirror(D, f) → D'
  7. Polygon(A', B', C', D') → q1', a', b', c', d'
  8. Segment(A, A') → g
  9. Intersect(f, g) → G
  10. Segment(B, B') → h
  11. Segment(C, C') → i
  12. Intersect(f, h) → H
  13. Intersect(f, i) → I
  14. Intersect(f, g) → J
  15. Distance(A, G) → distanceAG
  16. Distance(A', G) → distanceA'G
