The Penrose tiling is an unusual pattern that covers a surface with a pattern of flat shapes without overlaps or gaps. It involves applying translations, rotations, and reflections to determine if a shape tessellates. There are two types of tessellations: regular polygons and tessellations.
Regular polygons have all sides and angles congruent, and the sum of the measures of the angles at a tessellation vertex equals 360°. For a tessellation composed of polygons, the sum of the angles formed at any vertex equals 360°. For a tessellation composed of squares, the sum of the angles around each point equals 360°.
Tessellations can be created by starting with a basic shape and then using the sum of internal angles in a triangle as °. To tessellate a shape, it must be able to exactly surround a point, or the sum of the angles around each point in a tessellation must be 360 ∘.
The sum of the measures of the angles at a tessellation vertex is 360°
Non-regular tessellations are groups of shapes that have the sum of all interior angles equaling 360 degrees. The sum of an adjacent interior and exterior angle for any polygon is equal to 180 degrees since they form a linear pair.
In summary, tessellations involve covering a surface with flat shapes without overlaps or gaps. They can be created by applying translations, rotations, and reflections to determine if a shape tessellates.
