By far, the most famous number in NASCAR history is the #3 driven by the late Dale Earnhardt.  He was in third place when he fatally crashed on the last lap of the Daytona 500 on February 18, 2001.  #3 memorabilia still outsells all of the other drivers, even seven years after his death.

Tessellations

MC Escher Fish Pattern

There are three different types of tessellations:

  • Regular
  • Semi-regular
  • Irregular

There are three ways to make regular tessellations:

  • Translation
  • Rotation
  • Reflection

Tessellation Slideshow

Translation is the simplest and easiest tessellating design to make. The congruent shape is slid in both horizontal and vertical directions inside the grid. The finished repeated design fits together without gaps or overlaps.

 

Rotation is a tessellating design where the congruent shape repeats around a central point. The finished design is repeated in a circular pattern inside the grid.

 

Reflection is a tessellating design where the congruent shape is repeated in a different method from a translation. The shape is repeated by sliding and flipping in both a horizontal and vertical directions inside the grid. The finished design fits together without gaps or overlaps.
