TriangleTransformationGeometric Construction
This example demonstrates central symmetry (reflection in a point) for a triangle. It involves core math concepts like central symmetry and reflection transformation. Constructed using GeoGebra commands Polygon, Mirror, and Segment, it is suitable for middle school and above students to learn geometric transformation properties.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Mirror(A, O) → A'
  3. Mirror(B, O) → B'
  4. Mirror(C, O) → C'
  5. Polygon(A', B', C') → poly1', c', a', b'
  6. Segment(A, A') → d
  7. Segment(B, B') → e
  8. Segment(C, C') → f
