This example demonstrates how to perform reflections on the coordinate plane, involving core math concepts like coordinate transformation, symmetry, vectors, and polygons. It uses commands such as Polygon, Line, Mirror, and Segment in GeoGebra for construction, suitable for high school students learning coordinate geometry and transformations.

  5. Mirror(C, Line_1) → C'
  6. Polygon(A', B', C') → poly1', c', a', b'
  7. Segment(C, C') → g
  8. Segment(B, B') → h
  9. Segment(A, A') → i
  10. Line(D, G) → Line_2
  11. Mirror(A', Line_2) → A''
  12. Mirror(B', Line_2) → B''
  13. Mirror(C', Line_2) → C''
  14. Polygon(A'', B'', C'') → poly1'', c'', a'', b''
  15. Segment(C', C'') → l
