Face (geometry) - Wikipedia
In solid geometry, a face is a flat surface (a planar region) that forms part of the boundary of a solid object; [1] a three-dimensional solid bounded exclusively by faces is a polyhedron. A face can be finite like a polygon or circle, or infinite like a half-plane or plane. [2]
Face Definition (Illustrated Mathematics Dictionary) - Math is Fun
Illustrated definition of Face: Any of the individual flat surfaces of a solid object. Example: this tetrahedron has 4 faces (there is one face...
Face - Math.net
In geometry, a face is a planar (flat) surface of a 3D geometric figure. The figure below shows faces for two geometric figures, a cone, and a prism. Not all space figures have faces. For instance, a pyramid has faces but a sphere does not. A face is …
Vertices, Edges and Faces - Math is Fun
An edge is a line segment between faces. A face is a single flat surface. Let us look more closely at each of those: Vertices. A vertex (plural: vertices) is a point where two or more line segments meet. It is a Corner. This tetrahedron has 4 vertices.
Vertices, Faces and Edges - Definition, Example - SplashLearn
Vertices, faces, and edges are important elements of a geometric solid or shape. Learn about vertices, faces, edges of different 2D and 3D shapes with examples.

Visualizing Solid Shapes - Faces, Vertices, Edges of solid
Solid shapes are three-dimensional objects that have a length, width and height. Learn how to visualize solid shapes, what is a face, edge and a vertex, how to build solid shapes using nets and some solved examples on visualizing solid shapes.
Face -- from Wolfram MathWorld
2025年1月2日 · Generally, a face is a component polygon, polyhedron, or polytope. A two-dimensional face thus has vertices and edges, and can be used to make cells. More formally, a face is the intersection of an -dimensional polytope with a tangent hyperplane.

Face|Definition & Meaning - The Story of Mathematics
A face in geometry is a three-dimensional geometric shape’s planar (flat) surface. In short, the flat surface of a solid body is known as its face. It’s also important to realise that managing two-dimensional forms is physically impossible because everything around us has three dimensions.
