Tessellations are created using isometric transformations on an initial figure, that is, identical copies of one or several pieces or tesserae with which figures are composed to completely cover a surface. In mathematics, tiles can be generalized to higher dimensions. _.Ī mosaic of a flat surface is the covering of a plane that uses one or more geometric shapes, called tiles, without overlaps or gaps. N tessellation or tessellation is a regularity or pattern of figures that completely covers or paves a flat surface that meets two requirements: That there are no gaps That the figures do not overlap is not clear to you?. What is the sum of the angles of the equilateral triangles that meet at a vertex?Įquilateral triangle Three equal sides and all three angles are 60° Characteristics Sides 3 Vertices 3 What is the sum of the angles of the pentagons that share this vertex? The interior angles of the polygons that meet at a vertex must add up to 360 degrees. What is the sum of the angles of each vertex of a Tessellation? You have to go to the pentagons to find a polygon that does not tessellate…. What types of triangles do not tessellate on a surface? All triangles, and even all quadrilaterals including concave ones, tessellate the plane. What types of triangles do not tessellate a surface? Anytime you see a pattern made of identical pieces, shapes, or tiles, there is probably a tessellation. They are found throughout nature and in man-made structures. Like the tiles that cover a floor or wall, tessellations fit into a plane. Where can we find examples of tessellations? A tessellation (sometimes also called a tessellation) is when you cover a surface with a pattern of flat shapes so that there are no overlaps or gaps.
