decahedral

decahedral

A student holds a decahedral geometric model in math class.

Definition

Adjective: - Having ten faces: "decahedral" describes a polyhedron that possesses ten planar faces. This term is used primarily in geometry and crystallography to classify three-dimensional shapes.

Usage Examples
  • (The gemstone had ten flat surfaces.)
  • (A three-dimensional object with ten sides.)
  • (Crystals that develop with ten faces.)
Advanced Usage
  • "decahedral symmetry": a type of symmetry found in geometric shapes with ten faces.
    • The decahedral symmetry of the crystal was evident under the microscope. (The ten-faced arrangement showed balanced proportions.)
Variants and Related Words
  • Decahedron (noun): a solid figure with ten faces.
    • A regular decahedron is not a Platonic solid. (A ten-faced polyhedron.)
  • Decahedral (adj): describing something with ten faces.
    • The decahedral prism was used in the optical experiment. (The ten-faced prism.)
Synonyms
  • Ten-faced: having ten surfaces.
    • The ten-faced gem was rare. (Equivalent to decahedral.)
  • Polyhedral: having many faces (more general term).
