Understanding tessellations

The word tessellations may not be a familiar word to all of us, while tessellations are common in our everyday life. What exactly does it mean? Tessellations basically mean covering a surface without overlaps or gaps using a pattern of flat shapes. Using rectangular tiles to cover the kitchen floor is a good real life example of tessellations. We will learn more basic concepts of tessellations in this lesson.
