Question

question 9 of 10
a tessellation is an arrangement of repeating shapes that have what
characteristic?
a. any spaces or overlaps are small and randomly shaped.
b. no spaces or overlaps exist between its pieces.
c. its pieces lie on top of each other to generate beautiful artwork.
d. its pieces always consist of regular shapes.

Explanation:

A tessellation is a tiling of a plane using one or more geometric shapes (tiles) with no overlaps and no gaps. This is the fundamental characteristic of a tessellation. Options A and C are incorrect as they involve spaces/overlaps (which a tessellation doesn't have) or overlapping (contrary to tessellation rules). Option D is wrong because tessellations can be made with non - regular shapes too (e.g., some irregular quadrilaterals can tessellate).

Answer:

B. No spaces or overlaps exist between its pieces.
