    2 giorni fa · A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. In other words, all of its faces are the same size and shape (congruent) and all edges are the same length. A convex polyhedron in which all of its faces are equilateral triangles is the deltahedron.

  3. 2 giorni fa · Regular polygons, represented by Schläfli symbol {p} for a p-gon. Regular polygons are self-dual, so the rectification produces the same polygon. The uniform truncation operation doubles the sides to {2p}. The snub operation, alternating the truncation, restores the original polygon {p}. Thus all uniform polygons are also regular.

  4. 5 giorni fa · Uniform polyhedra may be regular (if also face-and edge-transitive), quasi-regular (if also edge-transitive but not face-transitive), or semi-regular (if neither edge- nor face-transitive). The faces and vertices need not be convex , so many of the uniform polyhedra are also star polyhedra .

    20 giu 2024 · The 120-cell is the compound of all five of the other regular convex 4-polytopes. All the relationships among the regular 1-, 2-, 3- and 4-polytopes occur in the 120-cell. It is a four-dimensional jigsaw puzzle in which all those polytopes are the parts.

  7. 24 giu 2024 · A regular polygon is both equiangular and equilateral. For example, a square has sides of equal length and angles of equal measure, and hence it's a regular polygon unlike a rectangle which does not have all sides equal. Similarly, a regular pentagon is a polygon which has all 5 sides equal and has all angles equal. Angle Sum Property.
