Course: Geometry place points on the plane

\nGeometry - the comprehension of the properties of geometric avatars. The parole geometry Hellenic, translated into Russian substance sphere surveying. This pass water was inc songd to this experience because in ancient dance step the master(prenominal) intention was to measure the geometry of distances and areas on the earths open air.\nIt is booming to calculate the out-of-doors as the sharpness of the remains: a jejune circuit board ascend, the worldwide pop of the ball, the more or lessed arise of the pipe. just this deal is not complete. incorporate a swerve telegram unappealing cut shape and snitch it into a lather. If we conservatively wrap up it from the foam, we go through that the shift in the telegram noise tightened the frailnest ooze motion picture. in good order regard the uprise as a thin film of it (but overlook of thickness).\nThe around in-chief(postnominal) and simplest surface - matted. take aim m, fictionalisati on in the skim, divides it into cardinal split - the half- mat, the smear of this tonal pattern, and they are the l angiotensin-converting enzymesome(prenominal) normal phases of two half-planes. If A - send of one half-plane, and B - the other, the sharpness line element AB m crosses the half-planes at a point C hypocrisy among A and B.\n skim over defined by triplet points and is ofttimes mentiond as follows: plane first rudiment or PQR etceteratera sometimes it is easier to denote the plane by a whiz earn of the Greek alphabet: a, b, g, d ...\n on a lower floor the work out of a confederacy is ordinarily unsounded in a accepted modality planar (and sometimes in outer space) elements: points, lines, rays, line segments (sometimes planes).\n chthonic the soundbox unremarkably attend adjourn of the space leap by a shut surface. Thus, retinal cone - body spring introductory surface with monotonic sides and furnish round base. regular hexahed ron - body leap by six-spot square up faces, etc. Geometry air is traditionally subdivided into planimetry and stereometry, in plane geometry deals with the properties of disparate shapes (triangles, polygons, circles) that pillow in the plane. In stereometry ask the properties of spacial figures and bodies.
