Line Segment Rotation

This example demonstrates the dynamic process of rotating a line segment around a point. It involves core mathematical concepts such as line segment, rotation, intersection, rectangle, division, cone, and arithmetic mean. The construction uses commands like Segment and Rotate with objects α (angle), O (center), A, B (segment endpoints), and transformed objects B', A', f, f'. Suitable for high school mathematics teaching to understand transformations and geometric constructions.
