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.
Convert this base tessellation into a more interesting shape. By following these steps, you ensure that your shape will always be able to tile the plane. If you find it easier to work from a rectangular base, but want your tessellation to have slide symmetry, cut off one of the triangular flaps and append it to the opposite side.
