**Vertices, Faces and Edges** space the 3 properties the define any kind of three-dimensional solid. A crest is the edge of the shape whereas a confront is a level surface and an edge is a directly line in between two faces. 3d forms faces, edges and vertices, different from each other.

In ours day-to-day life activities, we come throughout a variety of objects of various shapes and sizes. There room golf balls, doormats, ice-cream cones, coke cans and so on. This objects have various characteristic properties such together length, breadth, diameter, etc., which set them apart from one another. Yet no issue how various their dimensions are, every one of them occupy an are and have actually three dimensions. For this reason they are referred to as **three-dimensional forms or solids.You are watching: What is the difference between edges and vertices**

There are figures that deserve to be represented on a airplane (as a piece of paper) and have 2 dimensions, length, and breadth. And also they are described as **two-dimensional or airplane figures**. In this article, we will discuss the faces, edges and vertex definition in Maths for the heavy objects.

## What are Vertices?

The formal an interpretation for the vertex definition in Maths is characterized as a allude where 2 or an ext edges meet. Vertices are the corner points.

Cubes and also cuboids have actually 8 vertices.Cones have actually 1 vertex.Cylinders have actually no vertex.Spheres have actually no peak (the surface is a curve).## What space Faces?

Every individual flat surface the a solid is called its face. Solids have more than one face.

Cubes and cuboids have 6 faces.Cones have a flat face and a curved face.Cylinders have 2 flat faces and a bent face.A sphere has a bent face.## What are Edges?

The heat segment i m sorry acts as an interface in between two deals with is called an edge. Occasionally it is additionally described together the line segment joining 2 vertices.

Cubes and cuboids have 12 edges.Cones have actually 1 edge.Cylinders have actually 2 edges.Sphere has no edge.## Sides that Shapes

The native “side” is usually supplied for polygons such together a square has 4 sides, a triangle has actually three sides, a pentagon has 5 sides.

## Vertices, Faces and also Edges the 3D shapes

Let united state compare the vertices, faces and edges that solid shapes with the assist of a table.

Solid Name | Vertices | Faces | Edges |

Cube | 8 | 6 (square faces) | 12 |

Cuboid | 8 | 6 (rectangular faces) | 12 |

Cone | 1 | 2 | 1 |

Cylinder | 0 | 3 | 2 |

Sphere | 0 | 1 | 0 |

## Relation between Vertices, Faces and Edges (Euler’s Formula)

The relation in between vertices, faces and also edges deserve to be easily established with the assist of Euler’s Formula. Having actually learned about the faces, edges, and vertices that solids, permit us keep in mind an amazing relationship between the three of them. It is come be maintained in mind that the formula holds good for close up door solids i m sorry have flat faces and straight edges such as the cuboids. It can not be used for cylinders due to the fact that they have curved edges.

Euler’s formula is given by

F + V – E = 2

Where F, V, and also E are the variety of faces, vertices, and also edges the the polyhedra respectively.

## Solved Examples

Q.1: A cube has actually 6 faces, 12 edges and 8 vertices. Prove Euler’s formula for the cube.

Solution: Given, a cube has 6 faces, 12 edges and 8 vertices.

Therefore, according to Euler’s formula,

F + V – E = 2

Taking L.H.S.,

6 + 8 – 12

= 14 – 12

= 2 (R.H.S)

Hence, proved.

Q.2: How plenty of faces, edges and also vertices space there because that a triangle prism?

Solution: A triangular prism is a polyhedron that has actually 5 faces, 6 vertices and 9 edges.

## Frequently Asked questions – FAQs

### What are vertices, faces and edges?

Vertices space the corners that the three-dimensional shape, where the edges meet. Deals with are level surfaces and also edges space the lines wherein two faces meet.

### How numerous edges execute a cone have?

A cone has actually one flat surface and also one bent surface. Therefore, it has actually only one edge whereby both the surface meet. It has a curved edge.
