This document discusses dimensions from one to four dimensions. It defines dimension as the number of coordinates needed to specify each point in a space or object. One dimension refers to a line, two dimensions defines a surface with length and width, and three dimensions describes our everyday world with length, width, and height or depth. Four dimensions is also introduced. Examples of three dimensions in real life and computer graphics are provided. The last sections discuss the Khufu pyramid and geometric properties like the golden ratio found within its design.

4. Part 1: Definition of
dimension

6. Definition of
dimension

7. Definition of
dimension
•The dimension of a space or
object is informally defined as
the minimum number of
coordinates needed to specify
each point within it.

8. Part 2: One
dimension

10. One dimension

11. One dimension
•One dimension is actually
referring to a line.
•it can also be interpreted as the
point of moving into the line.
•it also refers to objects which has
no area and volume.

12. Part 3: Two
dimension

14. Two dimension

15. Two dimension
•To say that a surface is "two-
dimensional" means that, about each
point, there is a coordinate patch on
which a two-dimensional coordinate
system is defined.

16. Part 4: Three
dimension

18. Three dimension

19. Three dimension
•The three dimensions are commonly
called length, width, and depth (or
height), although any three
directions can be chosen, provided
that they do not lie in the same
plane.

•graphics that use a three-
dimensional representation of
geometric data (oftenCartesian)

37. Pyramid

39. Khufu Pyramid

40. Khufu Pyramid
• As a miracle of artificial
construction in the world,
the first pyramid of Khufu is
the world's largest pyramid,
built during the beginning of
Khufu pyramid height of
146.59 meters slope length
is 186.2967 meters.It is
featured with the bottom
edge length of 230.2628
meters, more than 250
million units, each weighing
about 2.5- - 50 tons of stone.

41. Khufu Pyramid

the first pyramid of Khufu is
the world's largest pyramid,
built during the beginning of
Khufu pyramid height of
146.59 meters slope length
is 186.2967 meters.It is
featured with the bottom
edge length of 230.2628
meters, more than 250
million units, each weighing
about 2.5- - 50 tons of stone.

43. The number of
"coincidences"

44. The number of
"coincidences"
• The perimeter of
the bottom of the
pyramid of Khufu,
if divided by the
height of the
double get
manufacturers to
3.14159, which is
pi.

45. The number of
"coincidences"
• The perimeter of
the bottom of the
pyramid of Khufu,
if divided by the
height of the
double get
manufacturers to
3.14159, which is
pi.

47. The number of
"coincidences"

48. The number of
"coincidences"
• It is nothing to
do with
coincidence that
the Khufu
pyramid
Meridian just
divide the
Earth's land and
sea into equal
areas.

49. The number of
"coincidences"
• It is nothing to
do with
coincidence that
the Khufu
pyramid
Meridian just
divide the
Earth's land and
sea into equal
areas.

51. Golden Ratio

52. Golden Ratio
•If the half of bottom
edge divide the pyramid
slope length (hypotenuse
distance), there will be
0.618.

54. • If you have a right-angle edge,

55. • If you have a right-angle edge,
• And you have a stick and a rope,

56. • If you have a right-angle edge,
• And you have a stick and a rope,
• How do you determine the other edge of the right
angle?
