Reflecting over Parallel Lines by Nicole Deiser

This example demonstrates the reflection transformation of points, line segments, or polygons across parallel lines and the resulting symmetry. Key math concepts include symmetry transformation, similarity transformation, properties of parallel lines, and the geometric meaning of reflection. The construction uses GeoGebra commands like Polygon to create polygons (vertices A, B, C, D, polygon object poly1) and auxiliary objects (a, b, c, d). Suitable for high school students learning geometric transformations, symmetry, and similarity, or exploring reflections in coordinate geometry applications.
