Who is specialized in Geometry? Come in and have a look.?

Aha, geometry!\n\nDraw a diagram and follow the steps below.\n\nThe trick is to show that the triangles DBE and \ntriangle DAF are similar.\n\nProof That triangles DBE and triangle DAF are similar.\n\nLet <ABC> donote angle ABC.\nWe need to show any two corresponding angles of these traingles are equal.\n\nFirst angle,\n<FDA> = <BDE>  because D,B,F collinear and D,E,A collinear.\n\nSecond angle,\n<DAF> = <DAC> because A,F,C collinear\n      = (pi) - <ACD> - <ADC> angles in triangle ACD\n      = (pi) - <ACD> - <ADC>  ...(1)\n\nNow, separately  manipulate,<ACD> and <ADC>.\n\n<ACD> = <ACB> + <BCD> splitting <ACD> with line CB\n      = <ACB> + <CAB>, tangent property <BCD> = <CAB> \n      = (pi) - <CBA>  angles in triangle ABC\n      = <ABE>  because C,B,E are all colinear\n\nNow, similarly\n\n<ADC> = <ADB> + <BDC> splitting <ADC> with line DB\n      = <ADB> + <BAD>, tangent property <BDC> = <BAD> \n      = (pi) - <ABD>  angles in triangle ABD\n         \nSubstituiting these two info into (1), we get,  \n\n<DAF> = (pi) - <ACD> - <ADC>\n      = (pi) - <ABE> - [ (pi) - <ABD> ]\n      = <ABD> - <ABE>\n      = <BDE> because BE splits <ABD> \n\nDone. In showing the triangle DAF and triangle DBE are similar.\n\nHence, by ratio for similar triangles,\n\n        DA/DF = DB/DE\n\nOr Rewriting we get\n \n      DA * DE = DB * DF\n\nProved.\n\nNot so difficult, was it. hehehe.\n\nRegards

Euclid.\nGreek 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. The text began with definitions, postulates ("Euclid's postulates "), and common opinions, then proceeded to obtain results by rigorous geometric proof. Euclid also proved what is generally known as Euclid's second theorem:  the number of primes  is infinite.  The beautiful proof Euclid gave of this theorem is still a gem and is generally acknowledged to be one of the "classic" proofs of all times in terms of its conciseness and clarity. In the Elements , Euclid used the method of exhaustion and reductio ad absurdum. He also discussed the so-called Euclidean algorithm  for finding the greatest common divisor  of two numbers, and is credited with the well-known proof of the Pythagorean theorem. \nNeither the year nor place of his birth have been established, nor the circumstances of his death, although he is known to have lived and worked in Alexandria for much of his life. In addition, no bust which can be verified to be his likeness is known (Tietze 1965, p. 8).

Been a while, so I'm not sure what you're looking for exactly in "Geometric Shapes".. but these might help somewhat.\n\nSun/Plannets - Sphere\nTree Trunk - Cylindar\nPine Tree - Cone\n\n\n...and my brain stops working.  but just for humor's sake...\nGood Looking Woman - hourgalss\n\n=D good luck with the homework

You've probably already been to this page, but maybe if you explained to the customer service rep. they'll give you a password. Good luck!\n\nhttp://www.harcourtcanada.com/school/math/geometry/tg.htm

Rene Descartes (the Cartesian coordinate plane plus many other contributions)\n\nPierre de Fermat\n\nBlaise Pascal\n\nLook them up. That can get you started. Personally, I'm going to bed.

It is quite obvious that since geometry is the instrument to design, and to design is to build an organized spacial structure, the knowledge of spacial forms is a necessary condition to deliver an architectonic message of the best quality. Moreover, with the introduction of computer design softwares, the possibilities of combinations of geometrical systems are enormously increased. And geometry is for the architect a disciplinal means, an essential implement in the "consideration" of the forms that intervene in the "composition" of space.

my school asked us to do just one: the daily applications of geometry (with special emphasis on Similar Triangle, Trig and Pyth theorem)

All the time.  Everything in computer modelling comes down to geometry.  Its all about the polygons (which are really just lots and lots of triangles)

You found one!\n\nBut seriously, are you looking for a particular person? Or a specialist in a particular field?\n\nIf you are looking for a particular person, then google is as good as anything else.\n\nIf you are looking for a specialist in a particular area of study, most universities' websites will have an area in which you can search for faculty by field of specialization.

First you have to know how to spell the various types of geometry: Euclidean, Non-Euclidean for a start. Then do a search for more informaiton.

It's been too long for me.\n\nSample many definitions. Go to MATHWORLD.COM (lower case)\n2 geometric figures are CONGRUENT when one gets transformed into the other by isometry.\n\nStay with it.\n\nGRIZZ

Non-Euclidean geometry is more general, spherical geometry is more specific.  There are several non-Euclidean geometries besides spherical - oblate spheroidal, cylindrical, etc.
