Symmetries Made Using Lists: Six Groups of Triangles with Slider Interaction

① This example demonstrates how to create a complex symmetric pattern composed of 6n triangles organized in six lists, using translation vectors and a slider for dynamic adjustment. ② Core mathematical concepts include 2D vectors, translation transformations, symmetry, and batch construction via the Sequence command, along with triangle types (e.g., scalene triangles) and a visual link to differential equations/calculus ideas. ③ Construction highlights: GeoGebra commands Sequence and Vector are used, defining points A, B, C and slider n; vectors u and v drive translations, while lists s0 through s5 organize the six triangle groups; dragging points or changing the slider alters the pattern's symmetry in real time. ④ Suitable for upper secondary to early university mathematics, especially for lessons on geometric transformations, vector applications, and dynamic math experiments, as well as for exploring symmetric patterns in design.
