These regions are- faces, edges, and vertices. Solid geometric shapes which have faces, edges and vertices are known as polyhedrons. Faces of 3D Shapes. The flat surface of a polyhedron is its face. WebRegular Polyhedrons. A polyhedron is said to be regular if its faces are made up of regular polygons and the same number of faces meet at each vertex. 1. This polyhedron is regular. 2. Its faces are congruent, regular polygons. Vertices are formed by the same number of faces. 1. This polyhedron is not regular. slushi the fox pfp

WebLesson 13 Summary. A polyhedron is a three-dimensional figure composed of faces. Each face is a filled-in polygon and meets only one other face along a complete edge. The ends of the edges meet at points that are called vertices. A polyhedron always encloses a three-dimensional region. The plural of polyhedron is polyhedra.
