How is geometry used in everyday life? When you're studying the subject, the science of lines and angles can seem like nothing more than a dull exercise in formulas and predictability. In reality, geometry is at work everywhere you go. Whether you're aware of it or not, geometry quite literally shapes our lives.
An Ancient Science
How long has geometry been around? To answer that question, let's take a look at where geometry gets its name. Geometry is derived from the Greek words for Earth (Geo) and measure (metria). It was put into practice by the ancient Greeks and continues to be used throughout the world today. It is the science of measuring shapes, angles, areas and distances. By the evidence the ancient Greeks left behind in their amazing ruins, such as the Parthenon, it's no doubt that they had a deep knowledge and understanding of the science of geometry.
Putting Geometry to Work
If you need an example of how geometry affects you on a daily basis, you need do nothing more than take a look around. What do you see? Maybe it's a bridge. Notice the steel girders underneath? They're arranged using very specific geometry angles to give the bridge its stability. Geometry also dictates the way your home was built, with angles and lines that make the walls sturdy and allow the roof to shed water and snow.
Maybe you see some people shooting pool. Ever wonder how pool players gauge their shots? They use geometric angles to try and estimate how the balls will react once they're struck.
If all this thinking gets to be too much, try drinking a can of soda. Ever wonder how they know that a can is exactly 12 oz? There's a geometric formula that dictates the can's size so that it contains exactly the right amount. The machinery that filled the can is also based on geometric formulas. People use similar principles when they're cooking at home. Cake pans and pots are all specific, standardized sizes that wouldn't exist if we didn't have geometry.
Without geometry, we wouldn't be able to build things, manufacture things or play sports with much success. Geometry not only makes things in every day life possible, it makes them easier by providing us with an exact science to calculate measurements of shapes, angles and areas. So the next time you're bringing a cake and soda to your poolshooting friends that live just over the bridge, you can thank geometry for bringing it all together.
If you've ever played pool, you've seen geometry and physics in action. Learning how to use the diamond aiming system on a pool table will show you just how important geometry is to the game of pool.

NonEuclidean geometry evolved from mathematical breakthroughs of the early 19th century, offering scientists a way to illustrate highly complex concepts of physics, space and time. 
Why is geometry important? Whether you're studying science or just playing a game of baseball, geometry is at work.
