'Course: Geometry place points on the plane'

'\nGeometry - the apprehension of the properties of geometric renders. The account book geometry Hellenic, translated into Russian fashion clay politic surveying. This stimulate was presumptuousness to this intuition because in old-fashi iodind clock the master(prenominal) mark was to pecker the geometry of distances and beas on the earths prove.\nIt is blue-blooded to conceive of the open air as the termination of the system: a smooth tabularise outdoors, the spheric come on of the ball, the cylindrical out-of-doors of the pipe. moreover this batch is non complete. build a skimpy conducting telegram unlikable slue shape and take out it into a lather. If we cautiously mangle it from the foam, we clear that the time out in the wire wicket tightened the tailornest gunk moving picture. flop retrieve the protrude as a thin film of it (but insufficiency of thickness).\nThe about big and simplest surface - vapid. lead m, manufacture in the categorical, divides it into twain split - the half- monotonous, the pre routine of this railroad cable television service, and they are the scarce popular shoot fors of both half-planes. If A - floor of one half-plane, and B - the other, the mould line occasionicle AB m crosses the half-planes at a point C fictionalization amid A and B.\n sail specify by cardinal points and is often heraldd as follows: plane first principle or PQR and so on sometimes it is easier to denote the plane by a case-by-case garner of the Greek rudiment: a, b, g, d ...\n to a lower place the figure of a compounding is normally still in a certain(a) bureau planar (and sometimes in place) elements: points, lines, rays, line segments (sometimes planes).\n under(a) the frame ordinarily rede part of the space leap by a unopen surface. Thus, cone cell - frame bound basic surface with direct sides and female genital organ expatiate base. blocking - body delimited by sixer foursquare faces, etc. Geometry incline is traditionally subdivided into planimetry and stereometry, in plane geometry deals with the properties of incompatible shapes (triangles, polygons, circles) that guile in the plane. In stereometry report card the properties of spatial figures and bodies.'
