Quitting smoking = depression? I quit smoking cigarettes seven days ago. I've quit before and I understand that this horrible loneliness and depression are just some of the withdrawal symptoms, but I don't know how to lessen the depression. Most of my friends are smokers, so I'm not going out much and I live alone.
A tessellation is a regular pattern made up of flat shapes repeated and joined together without any gaps or overlaps. These shapes do not all need to be the same, but the pattern should repeat. Another word for tessellation is tiling.
These tiles may be polygons or any other shapes. Many tessellations are formed from a finite number of prototiles in which all tiles in the tessellation are congruent to the given prototiles. If a geometric shape can be used as a prototile to create a tessellation, the shape is said to tessellate or to tile the plane.
