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.
Tessellations can be very useful in education and in teaching mathematics. They can be used from kindergarten to high school. Creating tessellations does not depend largely on numerical skills; therefore students with many different levels of mathe matical abilities can create them.
