This example demonstrates point rotation around a point in the coordinate system. Key mathematical concepts include rotation transformation and coordinate geometry. Using commands like Polygon, Rotate, and CircleArc, the rotated figure can be constructed. Suitable for middle school and above students learning geometric transformations.

GeoGebra Commands & Parameters
