Octahedron Geometry Diagram - Classic Mathematical Illustration #81414 (License: Personal Use)

This detailed line-art illustration depicts a regular octahedron-a Platonic solid with eight equilateral triangular faces, six vertices, and twelve edges. The use of stippling and parallel hatching enhances dimensionality, mimicking 19th-century scientific engraving techniques. It serves as both an educational tool and a design element for mathematical content.

Commonly used in educational websites, textbooks, or museum exhibits about geometry, polyhedra, or historical scientific illustration; targets students, teachers, and math enthusiasts seeking accurate, visually clear representations of 3D shapes.
