INTRODUCTION OF 3 D
MILD INTRODUCTION OF 3 D
Now we are going to plunge into the thrilling ocean of peaks
, vertices , faces .fringes and 3 d shapes. We are going to untangle the enigma of
vertices and fringes. It will enhance your sagacity .
I am greatly fascinated by glittering gift boxes. You might have seen those glossy gift packs .
These have many different shapes like triangles , squares, rectangles ,
cubes, spheres and pyramids. They have corners , surfaces , edges ,
surfaces and their linking sides.
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 dimensional shapes are called parts of 3 d shapes.
The point where two straight lines converge is called a 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 boundary is called edge or side. The interaction of all
these elements result in the creation of features of geometric figures .
A heroic formula was discovered by Euler which is given as following ;
V-E+F=2 In the above formula V represents the vertices, E represents
the edge and F stands for faces. They have an interesting application
in construction of buildings and 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 traverse through different shapes we can see the fascinating designs and link between
their parts for example there are shapes like cube or pyramid which are called polyhedron.
The interaction between edges , vertices and faces collectively make shapes .One prominent
family member of polyhedron is platonic solids. The solids that have all identical sides are
called platonic solids. Their examples are triangle ,hexahedron etc.
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 three dimensional shapes are all around us .
Geometry is a crucial part of the world . Geometry plays its role in the construction
of building ,fly-overs and skyscrapers . It also makes these structure steady and attractive .
The use of triangles and polyhedron in bridges and skyscrapers guarantees that the structures
are both strong and optically engrossing . There exists a strong relationship between
nature and geometry.
The love between nature and geometry is exemplary. We can see
geometrical shapes naturally in the helix of Mollusk‘s shells , scales and leaves
of flowers and bee hives .
So we can say that geometry is not only important in schools
but it is valuable in understanding the world around us. INTRODUCTION OF 3 D
CONCLUSION
INTRODUCTION OF 3 D
I hope that you have enjoyed the voyage . We have learned the building blocks of 3 d shapes.
They help us in solving the mathematical riddles and understanding the complex shapes .
They also appreciate the geometry .Whenever we are watching the astonishing building .INTRODUCTION OF 3 D
INTRODUCTION OF 3 D
We try to solve a confusing math problem or entertaining ourselves with the beauty of nature ,The golden concepts of geometry help us like a leading star.
