We spend so much time on cylinders and hexagons when we’re in primary school that it can get a bit old by the end of high school, but geometry is a key skill you’ll need throughout your life, so it’s worth paying attention.
Geometry is the maths we use to determine the size, shape, angle, and position of things, and it’s one of the oldest branches of mathematics – kids has to learn this stuff over 3,000 years ago. We are surrounded by things – us, our homes and schools, our cities and wild spaces – and geometry helps us measure all of these things and understand where they are. Without it, we would have no way of giving directions, knowing where to build a house, or even how to choose the right size water jug.
Which brings me to why geometry is important – you will use geometry without thinking all day long. Your skills will let you know if you are going to be able to pass through the door without getting stuck – and before you say that animals can do this and they don’t understand geometry that’s just not true.
You’ll also use geometry at work. In fact, if you have to measure or design anything, then you can expect you’ll need geometry.
Jobs that use geometry in real life
If I’m being real then every job needs a level of geometry, because we all need geometry – even office workers need geometry so they don’t all try to cram into the lift at once. But some jobs really need geometry, so if any of these sound like you then you might want to start paying attention in class:
Plumbers use geometry ALL DAY LONG
Every time they measure a pipe, fit a hose, or connect a tap, they’re making decisions about volume, space, shape, and size. A good plumber will be able to tell you exactly which pipe diameter they need to handle a set amount of water flow, and they’ll also be able to install it for you.
Pharmacists are masters of geometric dilution
That’s what you use when you mix a small amount of medicine with a substance that thins it out a bit, so it’s easier and/or safer to take. They use their maths skills (and some handy calculators) to work out which ratio is right for which patient. Find out more about becoming a pharmacist here.
Graphic Designers live for shape, size, and dimension
Whether they’re designing book covers or posters, t-shirts or even coffee cups, graphic designers need their geometry skills to ensure their designs grab the eye and fit on the t-shirt/cup/poster. To be honest, graphic design is more about math than art.
How will you use geometry in your life?
You already use geometry, so think about its many applications next time you’re bored in class. The skills you gain in maths make it easy for you to use geometry without even thinking when you need to.
