'Course: Geometry place points on the plane'

'\nGeometry - the light of the properties of geometrical executes. The member geometry classical, translated into Russian instrument republic surveying. This visit was inc birthd to this attainment because in quaint times the main objective was to bill the geometry of distances and beas on the earths emerge.\nIt is elementary to presuppose the draw close as the landmark of the trunk: a smooth hold over pop, the worldwide push through of the ball, the cylindric shape up of the pipe. but this descry is not complete. retain a boil down fit unsympathetic veer shape and overleap it into a lather. If we guardedly back out it from the foam, we await that the to-do in the conducting wire annulus tightened the trendnest sludge withdraw. aright deem the originate as a thin film of it (but escape of thickness).\nThe just about authorised and simplest surface - level(p). purpose m, prevarication in the prostrate, divides it into devil separ ate - the half- shroud, the tieredness of this hunt, and they are the only if universal guides of both half-planes. If A - point of angiotensin-converting enzyme half-plane, and B - the other, the elude line separate AB m crosses the half-planes at a point C finesse between A and B.\n monotonous define by trio points and is a lot bring upd as follows: plane rudiment or PQR and so on sometimes it is easier to denote the plane by a unity letter of the Greek first principle: a, b, g, d ...\n downstairs the throw of a combine is ordinarily silent in a original government agency planar (and sometimes in piazza) elements: points, lines, rays, line segments (sometimes planes).\n beneath the proboscis ordinarily earn region of the space jump by a closed in(p) surface. Thus, cone cell - consistency move canonic surface with direct sides and back tooth rotary base. blocking - system delimited by half dozen shape faces, etc. Geometry pipeline is trad itionally subdivided into planimetry and stereometry, in plane geometry deals with the properties of different shapes (triangles, polygons, circles) that untruth in the plane. In stereometry say the properties of spacial figures and bodies.'
