Chapter 7 Section 7.4

Objectives Learn about tessellations of regular polygons. Classify and identify monohedral, regular, and semiregular tessellations.

Tessellation A tessellation (tiling) is a pattern made of identical shapes where the shapes must fit together without any gaps and the shapes should not overlap. A tiling that uses only one shape is called a monohedral tessellation.

Regular Tessellation A monohedral tessellation of congruent regular polygons is called a regular tessellation.

Semiregular Tessellation When the same combination of regular polygons (of two or more kinds) meet in the same order at each vertex of a tessellation, it is called a semiregular tessellation.

Investigation As a class create semiregular tessellations using the floor tiles. What shapes could we use?
