This example uses GeoGebra to draw an octahedron for geometry teaching. Key mathematical concepts include the structure of polyhedra in solid geometry. By drawing vertices, edges, and faces, students can visually understand the composition of an octahedron. Commands used include Point, Octahedron, face, edge, etc. Suitable for high school geometry lessons.
