Работа с текстом ‘Geometric Solids’. На основе текста выполнить два задания.
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.

I have a dog Chick. He was only two years old but he already knows everything. He knows a lot of different teams. And execute them flawlessly! Chick very mobile so it does not get to walk.

I love the cow - it is thick , gives us meat, milk, cheese, cottage cheese , sour cream , butter and calves. I love it when a cow goes through the city on boats from the " Dior " and udders swinging and falls out of a cracked bra . I like to sleep on the warm cow's udder . I love stroking and silly moo cow - I giggle when the cow begins to mu - Flour . I love the look in her eyes resnischatye stupid , and the next day there is a pair of brains infused milk ... I love to whisper sweet and tender words in her ear , and drinking milk with her for a walk on the hay or a central avenue - and I love burgers and milk candy " Cow" . Cow shit is a useful fertilizer - wheat, nurtured in the fellow cow shit , give us bread. This bread we eat. Thank you cow.I also love the gorilla . She - sample force and an example to follow . Sometimes you want to hide behind the mighty hairy backs, while huge claws will tear enemies to pieces . Sometimes I do want to be wild gorilla , but not to worry shot - we have a lot of poachers .I like gorili little angry eyes and mouth oscherenny - with such a person can not only take Berlin , but also perform many other useful things - for example, working policeman .I love it when a cow gives gorilla banana, milk drinks and the two then long dancing cha-cha-cha under Ukrainian gray moon ...
