① This GeoGebra example dynamically constructs a Toblerone-like triangular prism and integrates an algebra and functions warm-up question, demonstrating the connection between solid geometry and function graphs. ② Core math concepts include prism construction, polygon rotation, interior angles, function graphs, linear regression, binomial and hypergeometric distributions, offering a cross-module synthesis. ③ Construction highlights: the Rotate command rotates polygons to form the 3D prism, Polygon defines the base triangle, InteriorAngles computes angles α, β, γ, with objects A, B, C, D, t1, a', b, a, t2, f, c, a_1, d, k, m, g, and text3 for annotations. ④ Suitable for high school or college preparatory students as a warm-up in algebra/function units, introductory solid geometry, or interdisciplinary project-based learning.
