In mathematics, 3-Dimensional shapes are a very important topic of geometry. In our day to day life, we deal with lots of 3-D objects which have length, breadth, and depth. All objects are of different sizes and shapes. For example, balls, ice-cream cones, books, etc. 

They all occupy space and are 3-D. Sometimes they are referred to as solids too. In this article, we will discuss various aspects of 3-D shapes with definitions and examples.  

They are made up of vertices, faces, and edges. We can say that vertices, faces and edges are the three main properties that define any 3-dimensional shapes of geometry. Let’s see what does each term mean in very simple language. The pointy bits or the corners of a shape where edges meet are known as vertices. 

Lines around the shape are known as edges. The flat sides of a shape that you touch when you hold a shape are known as faces. For example, the cube has 6 square faces, 8 vertices, and 12 edges, while the sphere has 0 faces, 0 edges, and 0 vertices.

Vertices

The vertex is written as vertices in plural form, usually denoted by capital letters such as E, P, Q, S, Z, etc. Vertex is a point where two or more curves, lines or edges of a shape meet. More specifically, a point where two or more lines of a polygon meet to form an angle or the corner is called vertex.

Faces

A flat surface or a plane region that creates part of the boundary of a solid object is known as a face. It is also known as the side of an object. For example, a cube has 6 faces, and a cylinder has 3 faces.

Edges

In geometry, an edge is a line that joins two vertices of a polygon. It is also known as a side. In simple language, an edge is a line segment on the boundary, or an edge is a line segment where two faces meet. For example, a pyramid has 8 edges, and cuboids have 12 edges.

Knowing the faces, vertices, edges properties of any objects lays the foundation for various industries such as architecture, interior design, engineering and more.
