ABSTRACT

This chapter considers how the complete rotation might be made up by examining the possible factors of 360°. 'Tessellation' simply means 'tiling'. The word comes from the Latin 'tessella', the small square stones used for making mosaic pavements. Shapes 'tessellate' if they can be used to cover a surface without gaps between them. These are made up from regular polygons of two or more kinds in such a way that the arrangement of corners is the same at each vertex. The tessellating pattern can be defined by writing in order the number of sides of the polygons which surround each vertex. A transformation of a given shape is a new shape where each point in the new shape is related in a particular way to a corresponding point in the original shape. The National Curriculum includes four types of transformations. These are translation, enlargement, reflection and rotation.
