    Текст для  аудирования: «The History of  Stereometry».

The first geometrical knowledge was originated from the practical needs of people in ancient times.

People measured distances, made straight spears and arrows, compared their length, etc.

     Farming and constructing played a very important role in the development of geometry. People worked out the new rules of comparing figures, calculating some geometrical values and volumes and the rules necessary for the construction of buildings. These rules appeared in Egypt and a bit later in China and India approximately in the 12th century B.C. In other words the age of geometry is no less than 4 or 5 thousand years

   Originally geometry was not a mathematical science though ancient Egyptians knew some facts of geometry such as the volume of a sphere, the Pythagoras theorem and some others. Geometry as a science got its further development in ancient Greece in the 7-5 century B.C.

Текст для чтения  «Geometric Solids».

    We have been studying plane figures which have only two dimensions; length and width. Now we will study figures with three dimensions. Figures that have three dimensions are called geometric solids or solid figures. The three dimensions are length, width and thickness or height.

PRISMS.A prism is a solid, each side of which is a polygon, and the upper base of which is parallel and congruent (exactly the same in size and shape) to the lower base; corresponding vertexes of the top and bottom polygons are joined by parallel edges. In a right prism the lateral faces (sides) are perpendicular to the bases.

Right prisms include; the rectangular prism and the cube. A geometric figure which has six sides, all of which are rectangles, is called a rectangular prism. If the dimensions (length, width and height) of a rectangular solid are equal, the solid is called a cube. The faces of a cube are squares.

THE RIGHT CIRCULAR CYLINDER.A cylinder is a circular prism, the bases of which are equal circles that are parallel to each other. If the sides of the cylinder are perpendicular to the bases, the cylinder is called a right cylinder. The axis of a right circular cylinder is the line between the centres of the bases.

A PYRAMID. It is a solid figure formed by a polygon called the base and sizes of triangles meeting at a common point called the vertex.

A CONE is much like a pyramid but has a circle for a base.
