In collections Playing With Symmetry
This example demonstrates the phenomenon of rotational symmetry, where a shape coincides with its original position after rotating by a certain angle. It involves core mathematical concepts like symmetry axes, rotation angles, and geometric transformations. The construction uses GeoGebra commands such as Rotate and Angle. Suitable for high school mathematics teaching or geometric transformation learning.
