Solids
Solids are particular shapes that lie in space. A solid has vertices, edges, and sides. For each solid, you can count its number of vertices, edges, and sides.Vertices |

Examples of solids
The cube |
The rectangular prism |
The prism |
 |
 |
 |
A cube is made of squares. A cube always has 6 sides, 8 vertices, and 12 edges. |
A rectangular prism is made of squares or rectangles. It has as many sides, vertices, and edges as a cube. |
A prism is made of 2 identical shapes linked together by segments. If the prism has a right angle we say it is a regular prism. On the drawing, the prism has triangular basis. |
The pyramid |
The cone |
The cylinder |
 |
 |
 |
A pyramid is made of a geometric form (triangle, square, hexagon,...) whose vertices
are linked up to the same point. The pyramid above is a pyramid with rectangular basis. |
A cone is made of a circle whose line is linked to one point in space. |
A cylinder is made of two circles linked together by segments. |
Pattern of a solid
The pattern of a solid in space, is the drawing you can create on a sheet which will enable you, if you fold it, to form the solid.Examples of patterns :
