# INTRODUCTION OF 3 D

## MILD INTRODUCTION OF 3 D

Now we are going to plunge into the **thrilling*** ocean* of peaks

**.**

*, vertices , faces***and**

*fringes***. We are going to**

*3 d shapes**the*

**untangle***of*

**enigma****and fringes. It will**

*vertices***your sagacity .**

*enhance*I am ** greatly fascinated** by

**. You might have seen those glossy gift packs .**

*glittering gift boxes*These have many

**like**

*different shapes***,**

*triangles**,*

**squares***,*

**rectangles****, spheres and**

*cubes***. They have corners ,**

*pyramids***,**

*surfaces**,*

**edges**surfaces and their

**sides.**

*linking*But you have never heard of their names.

## VERTICES

The ** corners **of these shapes are called vertices.

## FACES

The surfaces of these shapes are called* faces*.

## EDGES

The sides of these shapes are caked edges.

### PART OF 3d SHAPES

The ** building blocks** of three

**are called parts of 3 d shapes.**

*dimensional shapes*The

**where two**

*point***is called a**

*straight lines converge***.**

*vertex*## FACE

It is** defined **as the flat surface that forms the boundary of three dimensional shapes. INTRODUCTION OF 3 D

## EDGE

The ** line segment **on the

**is called**

*boundary**or side. The interaction of all*

**edge**these

*elements***in the**

*result***of**

*creation***of**

*features***.**

*geometric figures*A heroic formula was** discovered** by

*which is given as following ;*

**Euler**V-E+F=2 In the above formula V

*the vertices, E represents*

**represents**the edge and F stands for faces. They have an

**interesting**

**application**in

*and*

**construction of buildings***.*

**skyscrapers**## MEETING WITH SHAPES

Now , you are well ** aware of** the parts of these shapes , so we are going to study them

**.**

*practically*When we

**through**

*traverse***we can see the**

*different shapes*

**fascinating****and link between**

*designs*their parts for

**there are**

*example***like**

*shapes***or pyramid which are called**

*cube***.**

*polyhedron*

The interaction between edges , vertices and faces collectively make shapes .One *prominent*** family member **of

**is**

*polyhedron***. The solids that have all**

*platonic solids**sides are*

**identical**called

**Their examples are triangle**

*platonic solids.**etc.*

**,hexahedron**## UNLIMITED USES OF GEOMETRY

INTRODUCTION OF 3 D

There may be a ** question** in your mind ,”Where we can see these 3 d shapes? You will never

have to think about it because the

**shapes are all around us .**

*three dimensional*Geometry is a crucial part of the world . Geometry plays its

**in the**

*role**,fly-overs and*

**construction**

of buildingof building

**. It also makes these**

*skyscrapers*

*structure**and*

**steady****.**

*attractive*The use of triangles and polyhedron in ** bridges** and skyscrapers

**that the structures**

*guarantees*are both

**and**

*strong***engrossing . There**

*optically***a strong**

*exists***between**

*relationship*nature and geometry.

The love between nature and geometry is ** exemplary**. We can see

**naturally in the helix of**

*geometrical shapes**‘s*

**Mollusk***,*

**shells***and*

**scales**

**leaves**of

**and bee hives .**

*flowers*So we can say that geometry is not only * important* in

**schools**but it is

**in**

*valuable***the**

*understanding**us. INTRODUCTION OF 3 D*
