question 2 of 10
a regular tessellation is a tessellation that uses only one regular — to cover a surface completely.
a. polygon
b. octagon
c. parallelogram
d. rectangle

Explanation:

A regular tessellation uses only one regular polygon. Octagon (B) is a specific polygon but not the general term. Parallelogram (C) and rectangle (D) are not regular polygons (parallelogram has unequal side - length and angle in general, rectangle has right - angles but adjacent sides can be of different lengths). A regular polygon (A) is the general term that fits the definition of a regular tessellation.

Answer:

A. polygon
