It is initiative by class VIII level student to prepare presentation on geometry and its basic concepts

1. CONCEPT OF Geometrical
structures
FOR middle school LEVEL
My student from VIII
(ramesh prasad badoni)

2. Objectives
1. To imagine a structure or shape of
an object.
2. to start the drawing of the imagined
object.
3. to draw the various possible shapes
of the objects in their surroundings.
4. to apply these shapes to understand
the dimensions
5. to get an idea of formation of line,
area and volume of the structure

3. imagination of a structure
 regular shapes irregular

 regular shapes irregular
shapes
circle

cuboid
cylind octagonal
rectangle
triangle
cone

4. Thought process
Formation of a structure by combination of number of dot at a surface

5. What is a dot or a point
dots combinations at a surface
It is an imaginary mark
where from a unit formation
takes place

6. Role of a dot
joining of dots means formation of
--- Line
line

7. formation of axes

8. Dimensions
One dimensions or 1-D
Two dimensions or 2-D
Three dimensions or 3-D
Line
Area
Volume

9. What is a volume
When an area revolves or moves
about a line or surface means
volume is formed
area
area
volum
e

10. Now what is a line
line is the fundamental unit-cell
to form a structure/shape.
that means when a line moves about a dot it
develops a geometrical shape----- AREA
rectangle
circle
AREA
LINE

11. Formation of various
structures

12. formation of regular shapes from irregular
shapes
Area

13. formation of two and three
dimensional figures- EXAMPLES

14. Applications
world of geometrical shapes

15. some more interactions
