This example demonstrates 180-degree rotation in geometry. Key concepts include rotational symmetry and geometric transformations. Using GeoGebra commands Polygon and Rotate, the rotated figure can be constructed. Suitable for middle school and above students learning geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Rotate(A, 180°, (-1, 3)) → A'
  3. Rotate(B, 180°, (-1, 3)) → B'
  4. Rotate(C, 180°, (-1, 3)) → C'
  5. Polygon(A', B', C') → poly1', c', a', b'
