Reflection Exploration: Triangle in Prism with Integer Scatter Plot

This GeoGebra example demonstrates the construction of a triangle related to a prism using reflection transformations, along with an integer scatter plot to visualize corresponding points before and after reflection. The core mathematical concepts include reflection (axial symmetry), congruence, trigonometry, and the geometric representation of a prism. The construction uses commands such as Polygon, Intersect, and Line, involving objects P, L, H, Q, q1, a, b, m, w, C, D, f, and text1. By defining a reflection axis and computing intersections, the figure illustrates how shapes transform symmetrically. This resource is suitable for middle and high school students learning geometric transformations, congruence properties, and the connection between trigonometry and geometry, as well as for exploring the optical analogy of reflection in prisms.
