  1. In Euclidean geometry, a regular polygon is a polygon that is direct equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex, star or skew.

  2. Un poligono regolare è un poligono convesso che è contemporaneamente equilatero e equiangolo. Si tratta cioè di una porzione convessa di piano euclideo delimitato da una linea spezzata chiusa, formata da una successione di segmenti di uguale lunghezza, che formano tra di loro angoli di uguale ampiezza. Il nome poligono individua ...

  3. Regular Polygons - Decomposition into Triangles. Constructing Regular Polygons. Polygons are two dimensional geometric objects composed of points and line segments connected together to close and form a single shape and regular polygon have all equal angles and all equal side lengths.

  4. The following list of polygons, polyhedra and polytopes gives the names of various classes of polytopes and lists some specific examples. Polytope elements. Polygon (2-polytope) Vertex the ridge or (n−2)-face of the polygon. Edge the facet or (n−1)-face of the polygon. Polyhedron (3-polytope) Vertex the peak or (n−3)-face of the polyhedron.
