This example demonstrates the rotational symmetry of polygons by rotating the shape to show its axes and center of symmetry. Core math concepts include symmetry, rotation angles, and geometric transformations. Construction involves GeoGebra commands like Polygon and Rotate, using objects such as vertices A, B, C, polygon poly1, center c, and angle α. Suitable for middle school students and above learning geometric transformations and symmetry, or for classroom demonstrations.

GeoGebra Commands & Parameters

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