what is descriptive geometry?
612943
geometry using formulas and numbers, with good analytical description to show a problem or solution.\nIt does not rely on a picture, a diagram,nor solve a problem graphically. It solve a problem analytically.

A great one would be Euclid, a Greek geometer who wrote the "Elements", the world's most definitive text on geometry. The book synthesized earlier knowledge about geometry, and was used for centuries in western Europe as a geometry textbook. \n\nhttp://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Euclid.html\nhttp://scienceworld.wolfram.com/biography/Euclid.html\nhttp://mathworld.wolfram.com/Elements.html

A polyhedron is a geometric shape which in mathematics is defined by three related meanings.\n\nGO here- http://en.wikipedia.org/wiki/Geometric_solid

The essential difference between Euclidean and non-Euclidean geometry is the nature of parallel lines. In Euclidean geometry, if we start with a line l and a point A, which is not on l, then we can only draw one line through A that is parallel to l. In hyperbolic geometry, by contrast, there are infinitely many lines through A parallel to l, and in elliptic geometry, parallel lines do not exist.\n\nThe Möbius strip or Möbius band is a surface with only one side and only one boundary component. It has the mathematical property of being non-orientable. In Euclidean space there are in fact two types of Möbius strips depending on the direction of the half-twist: clockwise and counterclockwise. The Möbius strip is therefore chiral, which is to say that it is "handed".\n\nSo the Mobius strip is Euclidean.

Geometry is the the mathematics of the properties, measurement, and relationships of points, lines, angles, surfaces, and solids. it actually calculates all physical properties of objects that exist in this beloved universe.\nexample:\nhow to find the distance of an object using geometry.\nfirst you find the values that may bring a common relationship in all the various entities. then use the values obtained to find the most aproximate value of the property in which you are lookinf for in an object...\n\nwhy dont you just google it and you wil find all you need to know about geometry if I became detailed there wouldnt be enough space to explain the importance of geometry.

Metric spaces are abstractions that allow you to extend the ideas that you have proven for 1,2, and 3 dimensional Euclian space to other, more complex objects.\n\nGiven a set and a distance fuction (metric) defined on that set, if you can prove that they satisfy the requirements of a metric space, then you can apply all the theroems that have been proven for abstract metric spaces. That is, you can prove the same theorem over and over, or you can prove it once for metric spaces and carry it over to every metric space.\n\nWhen you have a theorem stated for an arbitrary metric space, think about what it says for the real line or the plane.

The only thing I remember about geometry is...a2 + b2 = c2.\n\nSomehow, I doubt that helps you.....sorry.

Descriptive Statistics do no intend to "fit" a distribution on the data or to predict new observations given the data.\nInstead, it pretends to "describe" the data in terms of its central tendency measures (mean, median, etc.) as well as dispersion statistics (variance,  rank, inter-quartile rank, etc.), bias statistics, etc.\nSummaries like histograms are also a good example of descriptive statistics.

Umm....do you want there definitions or what? Because coordinate geometry is just plotting a shape on the graph and then probably changing it with translation, rotation, reflection.....\nJust go type in those words to your question in yahoo or wherever you go to search and then look through untill you see a mathy kind of website. I suggest go and check www.regentsprep.org

hyperbolic\n\nare u not doing your own homework?\n\n\n\n\ntriangle drawn on a sphere always have total angles of more than 180 and they approach 180 as the triangle gets smaller. This type of geometry is called Elliptic Geometry.\n\nAnother type of geometry where all angles add up to less than 180, with 180 being the limiting case, is called hyperbolic geometry.\n\nThe geometry we r familiar with, geomatry of the flat is called Euclidean geometry.

Geometry is used in the field of surveying.\nProbability is used in all fields were estimation is required. It is also used in physics & science.\nStatistics are every-day things, like weather  charts, money spending, birth & death rates, etc.

Well I'm not a geometer ... so I may err slightly here as i only had one non-euclidean geometry class and going over some links has only refreshed some of it.\n\nRiemannian geometry is otherwise known as elliptic geometry :\n"It can be visualized as the surface of a sphere on which "lines" are taken as great circles. In elliptic geometry, the sum of angles of a triangle is > 180 degrees"  [this last part taken from mathworld]. It is a "non-euclidean" geometry "with positive curvature" which replaces the "parallel postulate" with *through any point in the plane, there exist no lines parallel to a given line.*\n\ntaken from wikipedia :\nSpherical trigonometry is a part of spherical geometry that deals with polygons (especially triangles) on the sphere and explains how to find relations between the involved angles. This is of great importance for calculations in astronomy and earth-surface and orbital and space navigation.\n\nSo one could say ... paraphrase the above defn of spherical trigonometry mentioning how it is a study of the relations of polygons, angles etc on objects under (or in) a riemannian geometry system\n\nincluded below are some of the links so you can formulate a better answer than mine :) gain a better understanding and even give examples that you find in those links and related links :)\n\nenjoy :),\nTom
