Question

1. which is not a necessary characteristic of a tessellation? repeating pattern congruent shapes striking color pattern no gaps or overlaps

Explanation:

A tessellation is a pattern of shapes that fit together without gaps or overlaps. It can be made with congruent shapes in a repeating pattern. However, the color of the pattern is not a necessary characteristic for a tessellation. The key elements are the geometric arrangement (repeating pattern, congruent shapes, no gaps/overlaps), not the visual appearance of color.

Answer:

striking color pattern
