how is geometry used in everyday life?

Sometimes geometry is more than calculating numbers.  Geometry has to do with shapes in space.\nSimple geometry is used when driving an automobile.  The curve of the road, for example is constant, so you do not have to keep adjusting the steering wheel.\nChildren use geometry when stacking blocks.  Adults use the same techniques when stacking boxes in a warehouse (they might also calculate how many boxes can go into the space provided).\nGeometry is used to make sure that a door closes in the frame.  Right angles and the proper length and width.\nGeometry is use when slicing a pie or cake.  Sometime to get even pieces, sometimes to get different size pieces.\nGeometry is used when playing baseball.  The diamond is really a square and the batter must place the bat at just the right place to hit the ball.  This is usually done unconsciously.\nAny time that size and shape of objects matter, geometry is used.

geometry got its importance universally.in medical engg for \nthe study of the various instruments used their geometry is to be known.for eg:an optical fibre used in endoscopic surgeries must of very fine geometry,or else it cannot serve the purpose.\nstill many examples can be coated.

Don't believe it when people tell you that you don't need to know geometry or algebra.  Depending on what you do in your life you may never have to prove that angles A and B are the same and you may never have to solve for X, but that doesn't mean that algebra and geometry aren't useful.\n\nThe purpose of learning math isn't so much to know math itself (although for some that's essential).  It's more about teaching you how to think.  Studying math helps you to think logically and dispassionately.  That can serve you well in life.\n\nAlso, algebra and geometry teach you how to think abstractly.  People who can't think abstractly tend to be very limited in their thinking and in their lives in general.  If everything you think about has to be concrete and obvious, you are going to be a very narrow person.\n\nIn my opinion, passing basic algebra should be an exit requirement for high school.

mikii, that's rude, though vinyl is rude and opportunistic as well. shut up if u dont have any answer.\n\nEuclide?\n\nAnyway, plane geometry is also called Euclidean geometry. this is a geometry where 2 parallel line never ever intercept and triangles alway have 180 degree of internal angles. u can imagine it as geometry on a flat plane as we know it. As for spherical geometry, 2 parallel lines do cross and the inside angle of a triangle is larger than 180 degree. how much larger depends on the curvature of the plane and the area of the triangle. U can imagine this geometry as one of the surface of a sphere. Spherical geometry is also called elliptic geometry.\n\nAnother popular geometry is called a hyperbolic. it's a geomtry of the pseudosphere. it's triangles have inside angles of less than 180 degree and 2 parallel line never intercept.

I took Geometry in high school, and while I thought it was a pretty good class, I wouldn't call it sacred.  What exactly is sacred geometry?

Approach your teacher and ask him or her whether your rule is geometrically valid. This is a very elementary costruction but you may have come up with something which exploits some neglected area of geometry. Once you interact, you will come to know whether it really is a brainwave or whether it already exists or is plain obvious.

Geometry is about thinking logically, as scientists do, or lawyers, or auto mechanics.  There are facts you have to know: the definitions, postulates, theorems.  And there are procedures you have to know: how to assemble the facts in a sequence that proves something.\n\nIn truth, not everyone is up to it.  Lots of people prefer to run their lives on a combination of emotion and simple beliefs and let other people do the thinking.  Maybe they're even happy.  But understanding the world well enough to make changes takes the kind of education that's based on hard mental work.

geometry:the pure mathematics of points and lines and curves and surfaces\n\nGeometry (from the Greek words Geo = earth and metro = measure) is the branch of mathematics first popularized in ancient Greek culture by Thales (circa 624-547 BC) dealing with spatial relationships

I hope I get this right, it has been a very long time since I took geometry and I was not very good at it. But here goes. Geometry is the mathematical study of lines, angles, circles, circumferences,triangles and the formulas needed to deduce these ordinary objects correct degree of angle or the volume contained within the circumference of an object. I think I may have left something out, but right now that is all I remember.

Mathematics (colloquially, maths or math) is the academic discipline that deals with such concepts as quantity, structure, space, and change. It evolved, through the use of abstraction and logical reasoning, from counting, calculation, measurement, and the study of the shapes and motions of physical objects. Mathematicians explore such concepts, aiming to formulate new conjectures and establish their truth by rigorous deduction from appropriately chosen axioms and definitions.[1]\n\nKnowledge and use of basic mathematics have always been an inherent and integral part of individual and group life. Refinements of the basic ideas are visible in ancient mathematical texts originating in ancient Egypt, Mesopotamia and ancient India, with increased rigour later introduced by the ancient Greeks. From this point on, the development continued in short bursts until the Renaissance period of the 16th century where mathematical innovations interacted with new scientific discoveries leading to an acceleration in understanding that continues to the present day.[2]\n\nToday, mathematics is used throughout the world in many fields, including science, engineering, medicine and economics. The application of mathematics to such fields, often dubbed applied mathematics, inspires and makes use of new mathematical discoveries and has sometimes led to the development of entirely new disciplines. Mathematicians also engage in pure mathematics for its own sake without having any practical application in mind, although applications for what begins as pure mathematics are often discovered later on

OK:\na good way to study geometry is as follows.\nin class, take meticulous notes. try using Cornell notes technique. works great,. google Cornell notes, for that.\nsecond. always study geometry right away, either after class, or before other subjects. its a hard subject therefore it should be done first.\nHome work problems should be done, while reviewing notes. if you get stuck, review notes or textbook. always try to memorize the important postulates and theorems. but don't just read them, try to understand them.\nexample, the area of a Rhombus is 1/2times the product of the diagonals.. if you don't understand what the names are, you won't understand the problem. diagonals means, segment from corner to corner. product is what you get when you multiply.. etc.. vocabulary is the most important part of geometry, specially the first part of geometry. usually the second semester is more algebraic in nature. \nthe first semester involves proofs, so language is extremely important.\nand after you done homework, always review, review. daily... give yourself enough time everyday for math.... do this on a regular basis and you can an A.. very possible.\nGood luck.

I'm going to focus on the usual non-euclidean geometry due to Lobachevsky. In that geometry, there are infinitely many lines parallel to a given line and through a given point. Squares (i.e. figures with 4 equal sides and 4 equal angles) don't have right angles. There is a pentagon with all right angles. The area of a triangle can be determined by the sum of the angles in the triangle (it is proportional to the difference of 180 degrees and the sum of the angles). There is a 'natural' unit of distance obtained from angles between parallel lines and perpendicular lines.

Yes, it is. We live with math every day. Even a person who barely finshed high school and struggling to make ends meet will use math everyday.\nExamples: Anything and everything to do with money. Paying bills, buying stuff, arranging mortgage etc.,\nCooking: You use ratios, propertions, fractions percentages, to figure out recipes when you are doubling them, halving them etc.\nIf you are decorating your house or working on your garden - you use a lot of geometry, like measuring out the floor space etc.\nDressmaking - You figure out the amount of material you would require - form of geometry my dear.\nThe list could just go on.\nIf you are on medication - the dosage is generally decided on --grams/kg body weight.\nOrganising your day - planning schedules, alarms, time management etc.\nand the list would go on.

Mainly in architecture (though computers do most of the work these days...).\nAlso, I have a friend who is an artist, and when she creates 3d work (sculptures, interactive art) she uses trigonometry and extremums to decide certain things (the best angle for a part of the work, how to use minimum material when she doesn't have a big budget etc.).\n\nBesides, it's pretty fun, if you like math.

You can give geometry a logical structure and build on the simplest of facts.\n\nThese basic facts are accepted as being true and they are called GIVENS.  Euclid, the Greek mathematician called them AXIOMS.\n\nSo,  in geometry we start with basic facts or givens such  as  'vertically opposite angles are equal.' \n\nFrom this small collection of givens you can begin to prove other facts in geometry.   For example, you can proove that the angles of a triangle add up to 180 degrees.\n\nYou can use these proofs to prove other more complicated 'facts' about geometric shapes etc.  The great thing is that when you try to do this you don't have to keep going back and prove all the other things.  This approach is called DEDUCTIVE PROOF.  \n\nIn mathematics proofs are considered absolute.  Once a proof has been made it will always be true.\n\nThe abbreviations and symbols that are used are essentially the same as algebra.  This is a key point because rather than dealing with numbers you use symbols and then the proof is true for all values.\n\nA proof has to be set out logically and ALL the steps should be shown.  As you build the proof you use symbols such the three triangular dots for 'therefore' and ==> for 'which gives.'  Words such as 'necessary'; 'sufficient' and 'converse' are also used.\n\nAt the end of the proof mathematicians used to write QED which is an abbreviation for the latin 'quod erat demonstrandum' which means 'which was to be shown or proved.'  I think that has fallen out of fashion and people write 'which was to be proved' at the end of end with the last line of the proof.\n\nThere are other methods for making a proof.

Cool question.  I would ask your teacher the same question.  Hopefully, they might be able to make some changes to make learning easier for you.  Having a good grounding in math is a very important building block for almost everything in life - especially when you learn geometry and algebra.  \n\nGood luck!

Hi. Euclid did a lot more than that. : http://www.answers.com/topic/euclidean-geometry-1\nGetting folks to think rationally about geometry was a great contribution.
