The cube is the only regular hexahedron and is one of the five Platonic solids . It has 6 faces, 12 edges, and 8 vertices. The cube is also a square parallelepiped , an equilateral cuboid and a right rhombohedron . It is a regular square prism in three orientations, and a trigonal trapezohedron in four orientations. The cube is dual to the octahedron .
How many lines of symmetry does a hexagon have? Credit: georigami CC-BY 2.0. The number of lines of symmetry in regular polygons is equal to the number of sides of the polygon. A regular decagon is a two-dimensional polygon with 10 sides of equal length, so it has 10 lines of symmetry. Most irregular polygons do not have a line of symmetry, with the isosceles triangle and rectangle serving as two exceptions.
