What is A type of art that uses a repeated pattern of interlocking shapes?

A type of art that uses a repeated pattern of interlocking shapes is known as tessellation. This technique involves creating a surface covered with a pattern of one or more geometric shapes that fit together without any gaps or overlaps. Tessellations are often found in tile work, mosaics, and certain styles of wallpaper. They are commonly associated with the work of the Dutch artist M.C. Escher, who explored their mathematical and visual complexities.
