Summary:

- Tessellations are geometric patterns created by repeating the same shape without any gaps or overlaps. They are commonly seen in art, architecture, and nature.

- Mathematicians have discovered that tessellations can be used to study and understand complex mathematical concepts, such as symmetry, transformations, and tilings.

- Tessellations have practical applications in fields like computer graphics, materials science, and biology, where they can be used to model and analyze various structures and patterns.
