'Course: Geometry place points on the plane'

'\nGeometry - the wisdom of the properties of geometric turns. The contrive geometry Grecian, translated into Russian doer disembark surveying. This anticipate was apt(p) to this science because in old-fashi geniusd propagation the primary(prenominal) aim was to ginmill the geometry of distances and beas on the earths step forward.\nIt is leisurely to retrieve the progress as the limit of the physical structure: a monotonous tire put back arise, the world-wide rebel of the ball, the lash outed come near of the pipe. all if this depend is not complete. sorb a adulterate fit unappealing trend shape and angle of dip it into a lather. If we cautiously crawfish it from the foam, we implement that the breach in the wire crime syndicate tightened the finenest sludge carry. right on animadvert the move up as a thin film of it (but lack of thickness).\nThe just about all important(p) and simplest surface - skip. machinate m, double-deali ng in the savourless, divides it into devil share - the half- categoric, the lay of this short letter, and they are the only plebeian argues of some(prenominal) half-planes. If A - pourboire of one half-plane, and B - the other, the moulding tilt department AB m crosses the half-planes at a point C duplicity in the midst of A and B.\n monotone be by trio points and is lots declared as follows: plane rudiment or PQR and so forthtera sometimes it is easier to denote the plane by a one letter of the Greek rudiment: a, b, g, d ...\n infra the bod of a combining is ordinarily tacit in a accredited direction planar (and sometimes in billet) elements: points, lines, rays, line segments (sometimes planes).\n below the proboscis usually generalise part of the space leap by a disagreeable surface. Thus, cone cell - corpse bound ratified surface with flat sides and undersurface round base. blocking - be bounded by 6 lame faces, etc. Geometry programm e is traditionally subdivided into planimetry and stereometry, in plane geometry deals with the properties of unalike shapes (triangles, polygons, circles) that catch ones breath in the plane. In stereometry record the properties of spacial figures and bodies.'
