Octahedron Demonstration

This example demonstrates the construction and basic properties of an octahedron. The core mathematical concepts involved include polygons, solid geometry, and parametric equations. Key GeoGebra commands and objects used in the construction, as extracted from the summary, are RotateText (rotating text), Sphere (sphere), Intersect (intersection), Polygon (polygon), Pyramid (pyramid), and Segment (segment). It is suitable for high school and above students studying solid geometry, spatial figures, and parametric equations.
