Triangular Prism Construction in GeoGebra

① This example demonstrates a triangular prism in a 3D GeoGebra workspace, visualizing its vertices, edges, faces, and overall spatial arrangement. ② Core mathematical concepts include solid geometry: the definition of a prism, polyhedron faces (bases and lateral faces), edges, vertices, and spatial relationships among points, lines, and planes. It also implicitly involves sequences (generating point lists), polygons (forming the base triangle), and the Prism command to create the 3D solid. ③ Construction highlights: from the summary, the Sequence command generates a series of points (e.g., A, B, C), Polygon creates the base triangle poly1, and Prism builds the prism using a base and a top point (e.g., B_1). Named objects include faces (faceBCD, faceABCE, etc.) and edges (edgeBC, edgeCD, etc.), which facilitate further measurements or animations. ④ This is suitable for high school or early college students learning solid geometry, for teachers demonstrating prism properties in class, or for students exploring cross-sections, surface area, and volume calculations interactively.
