The number of edges of any polyhedron can be calculated using the formula: E = V + F - 2, where "E'" denotes the number of edges, "V" indicates the number of vertices and "F" represents the number of faces. It is derived... More » Math Geometry Shapes

A pyramid with a hexagon-shaped base has 12 edges, seven faces and seven vertices (points where edges meet). The qualities of a polyhedron are intrinsically related to one another, as is shown using an equation called Eu... More » Math Geometry

A tetrahedron is a three-dimensional shape that contains four vertices, four faces and six edges. This Platonic solid is classified as a polyhedron, specifically a regular convex polyhedron. This indicates that all the f... More » Math Geometry Shapes

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though... More » Math Geometry Shapes

A tetrahedron is a three-dimensional object that has four faces, six edges, and four vertices, or points. It can be thought of as a pyramid with a triangular base. Regular tetrahedrons are made of four equilateral triang... More » Math Geometry Shapes

A sphere has no faces, edges or vertices. By definition, it is a curved three-dimensional geometric figure whose surface is defined as the set of all the points equidistant from its center point. More » Math Geometry Shapes

A hexagonal prism has 12 vertices, along with eight faces and 18 edges. This shape has two hexagonal sides, as well as size rectangular sides that connect the sides of the hexagons. More » Math Geometry Shapes
