1.     Go on the Internet and find a simple definition of the word tessellation.

                 A tessellation or tiling of a plane is a pattern of plane figures that fill the plane with no overlaps and no gaps. A tessellation is created when a shape is repeated over and over again. All the figures fit onto a plane / flat surface exactly together without any gaps or overlaps.

Copy and paste different pictures of tessellations in the Alhambra.









Observe carefully different pictures of tessellations in the Alhambra and read the following definition:

A tessellation is a repeating pattern composed of interlocking shapes (usually polygons) that can be extended infinitely. The tiling for a regular (or periodic) tessellation is done with one repeated congruent regular polygon covering a plane in a repeating pattern without any openings or overlaps. Remember 'regular' means the sides of the polygon are all the same length, and 'congruent' means that the polygons fitted together are all the same size and shape. A semi-regular (or non-periodic) tessellation is formed by a regular arrangement of polygons, identically arranged at every vertex point.
