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.
However, tessellations can be very complex. Any figure can be used, not just geometric shapes. Unfortunately, the number system that we used to name our previous examples would not apply to these tessellations. The naming system is used when the tessellation is made of regular polygons, but not for other shapes. For example, if a tessellation has a 10-sided star, there would be no way to determine if the 10 in the name represented a star or a decagon.
