Geometry is used in many areas of real life. It is primarily developed to measure lengths, areas, and volumes and is used for practical applications like carpeting, gardening, and conical hats. Geometry is also important in fields like computers, where software uses coordinate geometry as a basis. It has applications in photography through use of lighting angles, in stairs through inclined angles, and in physics through equations of motion. Geometry is key in graphics design, buildings, vehicles, cycles, surveying, and other areas involving shapes and spatial relationships.

3. Geometry is one of the classical disciplines of math.
Roughly translating in Greek as "Earth Measurement", it is concerned with the properties of space
and figures.
It is primarily developed to be a practical guide for measuring lengths, areas, and volumes, and is
still in use up to now.
What is Geometry?

5. Basics:

6. You wants to new carpeting for your
living room.
Your living room is an 8 m by 8 m
rectangle.
How much carpeting do you need to
buy to cover your entire living room?
You need to find the area for this
Area = 8 m × 8 m = 64 m2
Applications of Area

7. you have a rectangular flower
garden that is 10 ft
long and 2 ft wide. One bag of soil
can cover 10
ft2. How many bags will you need to
cover
the entire garden?
Find the area first and then
calculate how many bags are
needed.
Area = 10 ft * 2 ft = 20 ft2
# bags = 20 ft2 ÷ 10 ft2/bag = 2
bags
Applications of Area

8. For a party, you made about 10
conical hats out of cardboard. How
much cardboard was used in total if
each cap has a radius of 15 cm and
a slant height of 25 cm?
Applications of volume

9. Let's say you want to fence a garden.
Find the perimeter to answer this
question. Add up all four sides to get
the perimeter - 40 +20 + 40 + 20 = 120
feet. You will need 120 feet of fencing
to enclose your garden
Applications of perimeter

10. Subject
Camera
 The reason that 45 degree
lighting is so important is that
it’s the perfect angle to create
modeling on the human form.
 The term modeling refers to
showing three dimensionality
through the use of light.
 When you have light coming
from where the camera is, that
three dimensionality is lost
because shadows aren’t seen
on the face.
 Put the light off the camera
and you get shadows, which
gives you 3D, and 45 degrees
is the perfect angle to
maximize this effect.

12. Geometry is part of the fundamentals of any type of design. It
makes use of the angles and relationships between shapes,
which will eventually for parts, arches, hallways and anything
else designed on a computer.
In computers, there are various software like AUTOCAD, Unity,
3DS MAX etc. These software are used for the various 2D & 3D
applications and games and are mainly based on geometry or
rightly said as coordinate geometry. These programs are used
by architects and various developers to develop various 3D
models as a blueprint or pre-design. In basis computing also
geometry is used for various purposes like placing of pixels, MS
Paint, movement of cursor on screen on the screen.

14. Geometry has a deep relation with physics since history. It is widely used to prepare the equations for
the projectile motion, the path of trajectory etc.
Trigonometric geometry can be easily used to solve many problems of physics in problems on work
an vector quantities as the include trigonometric values. Geometry is also used to find the direction
of the force exerted by a magnetic field with the help of a tangent. It can also be used to find the
direction of the force exerted on the when it is in circular motion.

18. A graphic designer studies how basic geometric shapes combine into artistic visual layouts
in two and three dimensions. A graphic artist uses geometric concepts such as perspective
and golden ratios to create the most pleasing designs. He uses computer graphical tools
that break complex, realistic images into many basic circles, lines and polygons.
