VectorTransformationGeometric Construction
This example demonstrates the geometric phenomenon of plane mirror reflection. Key mathematical concepts include reflection, vectors, and geometric construction. Using GeoGebra commands such as Line, OrthogonalLine, Mirror, and Segment, the principle of reflection is visually illustrated. Suitable for middle school and above students or teachers.

GeoGebra Commands & Parameters

  1. Line(A, B) → a
  2. OrthogonalLine(C, a) → b
  3. Mirror(D, a) → D'
  4. Mirror(D', b) → D''
  5. Mirror(D'', a) → D'''
  6. Segment(A, B) → c
