Geometric Reflection Exploration

This GeoGebra example demonstrates how to construct polygons and explore their reflection transformations across a line. The core mathematical concepts include geometric reflection properties, coordinate changes after reflection, and axisymmetric characteristics. Construction details: Using the Line command to draw the axis of symmetry, the Polygon command to create polygon vertices (A, B, C, D, E, etc.), and reflection commands to generate symmetric figures while observing the positional relationships of corresponding points. Suitable for middle school to high school mathematics curricula, this example helps students understand axisymmetric concepts and master basic geometric transformation methods, serving as an intuitive demonstration tool for learning coordinate transformations in analytic geometry.
