Why is geometry important? You may be thinking to yourself, "When will I ever use this stuff? Why do I need to know this?" Geometry is an important science that not only influences a great many other sciences, but your everyday life as well. If you feel like you've drawn yourself into a corner with geometry, the following will help get you out.
Geometry and Science
People need to learn geometry because of the way it affects us on a daytoday basis. Having a grasp of geometry constructions helps us better understand the world around us. Whether you're playing a game of Tetris or piloting a spaceship, you're using principles of geometry to guide your decision making.
Let's say you want to be an architect. It's much more than just designing buildings that look cool. You need to know precisely how shapes and angles fit together to maintain stability. After all, you don't want to design a house that crumbles. Geometry is what is keeping a roof over your head right now. Take a look at a house that's being built, and you'll see angles everywhere. Architects, engineers and builders use these angles to keep a house stable in high winds and to withstand the weight of everything inside.
Perhaps you're interested in becoming a technician for NASA. Physics is a science that draws upon analytical geometry to calculate shuttle launches and missions. The orbit of the moon around the Earth is a geometric equation that is essential in navigating to and from our only natural satellite. When a shuttle docks with the International Space Station, it's the result of weeks of geometric calculations to make sure that the shuttle leaves Earth and reaches the station at the right height and speed. There's only so much fuel available for the Space Shuttle, and there's no rocket fuel stations in space, so a minor error in those calculations could mean scrapping a mission.
Geometry in Life
What if you're not interested in becoming an architect or Space Shuttle pilot? Geometry can be used in other practices as well. If you're into sports, what you may refer to as a football is actually an oblong spheroid. The specific shape of a football affects the way it reacts when tossed. Understanding this can give you a better edge of throwing that perfect spiral.
If you like baseball, you've seen geometry at work. The angle of a pitch and the angle where the bat meets the ball makes the difference between a high popup to the infield and a deep shot for a home run. Pool games are all about geometry. You need to know your angles so you can bank shots across the table and understand where your cue ball will rest at the end of the shot.
Geometry is a complex science, and many people don't have an everyday need for its most advanced formulas. Understanding basic geometry is essential for everyone, because you never know when the ability to understand an angle or figure out the area of a room will come in handy.
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.
