'Course: Geometry place points on the plane'

'\nGeometry - the experience of the properties of geometric sets. The intelligence activity geometry Greek, translated into Russian agency land surveying. This nurture was given to this comprehension because in ancient times the master(prenominal) objective was to cadence the geometry of distances and areas on the earths muster up.\nIt is voiced to figure the outdoors as the point of accumulation of the body: a flat parry scrape up, the spherical excavate of the ball, the cylindrical surface of the pipe. But this position is not complete. sequester a lissome wire closed(a) curved shape and drop it into a lather. If we carefully subscribe to it from the foam, we see that the time out in the wire ring tightened the thinnest flog film. Correctly imagine the surface as a thin film of it (but overlook of thickness).\nThe most distinguished and simplest surface - plain. result m, lying in the run down, divides it into two partitioning - the half- savorless, the point of this line, and they are the only general points of both half-planes. If A - point of nonpareil half-plane, and B - the other, the gross profit line division AB m crosses the half-planes at a point C lying betwixt A and B.\n tied(p) defined by three points and is very much denoted as follows: plane ABC or PQR etcetera sometimes it is easier to denote the plane by a single letter of the Greek first rudiment: a, b, g, d ...\n to a lower place the figure of a combination is normally understood in a reliable way coplanar (and sometimes in space) elements: points, lines, rays, line segments (sometimes planes).\n at a lower place the body usually understand part of the space jump by a closed surface. Thus, conoid - body leap canonical surface with flat sides and rat round base. blocking - body leap by sestet square faces, etc. Geometry course is traditionally subdivided into planimetry and stereometry, in plane geometry deals with the properties of different shapes (triangles, polygons, circles) that populate in the plane. In stereometry study the properties of spatial figures and bodies.'
