What are examples of Geometry found in the real world?

Answer 1

Do you mean, What will I ever use this for?
Any field where you draw or design or build or tear down...construction, demolition, architecture, HVAC, landscape, art, printing lay-out, arborist.

If you ever want to paint a room you will need to determine surface area. Fence the garden? Gotta find perimeter.
Need a new roof? Gotta find the area.
Re-seed the lawn? Gotta find area there, too.
New furnace or air conditioner? Gotta know the volume of the space you want to heat or cool.

Even the formal idea of proof that is usually first introduced to students in high school geometry is wildly useful in other fields like science and even writing. Thinking in that step by step way and causing another to follow your reasoning, perhaps changing their mind in the process...politics. Many lawyers take an under grad degree in math. The law is very much like doing proofs...Does this meet the definition is a question asked in both geometry and law.

Hope this helps.

Answer 2

In quality control you use probability every day. You have a machine making some kind of widget that has a dimension that must be held within certain tolerances. You take 25 parts and measure them, then do what's called a 'capability study' to see if the machine is able to get them all within limits, or if you need to use a better machine. Another place probability is used is in insurance. They have people called 'actuaries' who compile statistics to see what the probability is of someone dying in the next year, the next five years, ten years, etc. Someone who smokes is more likely to die. Or someone who takes antidepressant meds, or has a history of heart problems, etc. They figure out how each of these factors affects the person's probabilities, and they figure this into the rates. Big powerful corporations often sell products they know are not as safe as they could be. There was a famous case back in the 1970s with the Ford Pinto. Millions of these cars were sold with a defect that could cause the gas tank to explode if the car was hit from behind. After they found out about it, they did a probability analysis and found that it would be cheaper to just let it happen, and defend themselves against the resulting lawsuits, than to recall all the cars and fix the problem.

Tons.

Let us start with your house. You do not have a crooked house, right. Because builders and carpenters have to make sure that all their walls are PERPENDICULAR. And one way of assuring things are perpendicular is that you must know Pythagorean Theorem. Remember that?

Also, you must know how big your room is by calculating the area and height. If you don't know how, including the use of units, you may end up a closet-sized room. Not good if you are a 250 lb seven footer.

Geometry is important in transportation. Have you seen a car with square wheels? And how do you calculate the number of miles you travelled? The odometer calculates it indirectly by knowing the circumference and radius of the tires and how many times it has been turning. If your tire revolves or turns from start to end of the circle is 6 feet, then if your car have been speeding so that the tires turn 1000 times in one minute then you just drove 6,000 feet in one minute. This is approximately over a mile a minute or about 60mph.

Or about food. Notice how diverse and interesting the packages are? You wheaties come in rectangular boxes or prisms, ice cream in cylinders, soy milk in nice looking parabolic shaped container, nicely shaped melons are spheres, and ice cream cones are yes, you guessed it conic.

So, you see it is everywhere. We just kinda take it for granted.

Answer 4

ripples are concentric circles, snowflakes are symmetric (4,5,6,7,8 sided... there's a great book out right now 'The Little Book of Snowflakes' by Kenneth Libbrecht). The human body is roughly bilaterally symmetric (right and left side are mirror images) as are almost every animal in the world. The world is a sphere, the solar system is composed of eliptical orbits.... but that's not "found in the real world". Flowers are symmetric. Crystals are geometric in shape (salt crystals for example). I could go on.

Answer 5

- The monitor you're reading this on (screen size is based off diagonal measure, so the Pythagorean theorem comes into play)
- The structure of certain molecules and ions (the molecular structure for salt for example is cube-shaped, whereas methane is tetrahedronal).
- Dice (multi-sided dice like the kind used for role-playing games are often based off platonic solids, as these give shapes where every face is the same size and shape and everything is symmetrical)
- The construction of musical instruments, many shapes of which are based off of mathematical formulae
- manhole covers (if they weren't circular, they could fall through the hole)
- Various forms of engineering (for example, trying to find the shape of a container that will give a maximum amount of volume for a minimum amount of costly surface area)
- How many examples do you need?

Answer 6

Geometry is everywhere.
You don't think they build houses the way they do because they look nice. If they could, they'd make the weirdest houses ever.

Answer 7

you mean geometric principles? because you can't look without seeing triangles, squares, cylinders...

I use Pythagorean theory all the time in carpentry and art projects.

When pizza companies want to figure costs (say they want to reduce or increase pizza size) they gotta know how to figure the area of a circle.

Area of a rectangle or square? every homeowner uses this whether to figure carpet, grass seed or paint.

Answer 8

When engineers design things such as bridges and damms they rely on their understanding of geometry immensely.

Answer 9

The Pentagon, stop signs, truss bridges, roofs and floors.

Answer 10

The building or house you live in-
