Reflections on the Coordinate Plane

This example demonstrates how to perform reflections of points and line segments on the coordinate plane. It involves core mathematical concepts such as coordinate transformation, symmetry, and the properties of reflection. The construction uses GeoGebra commands like Polygon, Line, and Mirror, along with objects A, B, C, t1, c, a, b, D, E, f, A', B', C', t1', c', a', b'. Suitable for middle school and above students learning coordinate geometry and geometric transformations.
