In collections Transformation-Rotation rotations
This example allows students to explore 2D rotation through simple geometric transformations. It involves the core mathematical concept of rotation transformation. Using GeoGebra commands Polygon and Rotate, the construction of rotated figures is demonstrated. Suitable for students at the junior high school level and above.

GeoGebra Commands & Parameters

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