Rotations Exploration 2: 180° Rotation (Student Copy)

This example demonstrates the geometric transformation of rotating a plane figure by 180 degrees about a point, showing how the pre-image and image relate, with corresponding points connected through the center and bisected by it. The core mathematical concept is rotation, specifically central symmetry (180° rotation is equivalent to point reflection). Although no explicit GeoGebra commands are listed in the construction summary, typical construction involves using the rotation tool or Rotate command, possibly with a slider or fixed angle, and using vectors or a coordinate grid for visualization. Suitable for middle school geometry, this helps students understand rotation properties, central symmetry, and serves as a template for independent exploration.
