Which of the following is not a condition of a Tessellation?

1-it must be composed of one shape

2-it must be completely cover a surface

3 - it must have a repeating pattern

4-it must have no gaps or overlapping

The answer would be 1. Tessellation involves tiling and is a display of shapes fitted together on a surface, which means that tessellation does not only compose of one shape. It has to have a repeating pattern with no gaps. That can be achieved with a variety of shapes.
