"Fishes"

A special type 2 pentagon is the basis for this pattern. Type 2 tiles have two non-adjacent angles which when added together equal 180 degrees. They also have two sides of equal length which join at one of those two angles. This pattern requires that four sides of the pentagon will be of equal length and two of each will join to form the two angles which eaqual 180 degrees. The remaining side can be of a different length.
