Spiral Mihai V: Polygonal Rotation and Translation Forming a Spiral Surface

① This example demonstrates a visual phenomenon where a series of polygons, rotated and translated in a plane, progressively stack to form a spiral-like solid surface that culminates in a conical shape. ② Core mathematical concepts include polygons, rotation, translation, spiral curves, surfaces, and rational number ratios, bridging plane geometry and solid geometry. ③ Construction highlights: Based on the construction summary, the example uses GeoGebra commands such as Polygon to create multiple polygons (poly1 to poly6), OrthogonalLine to construct perpendicular lines, Intersect to find intersection points, and Segment to connect key points, forming a continuous polygonal chain; objects include points A, B, C, D, E, F, G, H, I, J, K, L, M, N, and lines f, g, h, i, j, k, l, m, n, p, q, r, s, t, a, b, c, d, e, f_1, which are transformed via rotation and translation to generate a spiral arrangement. ④ Suitable for high school or early college students to explore geometric transformations and surface generation, and also useful as material for mathematical art design or dynamic geometry demonstrations, helping to understand how a polygonal chain extends spirally in space and relates to a conical surface.
