Answer:
squares
Explanation:
A tessellation is a tiling of a plane with shapes in such a way that there are no gaps or overlaps. Squares have the unique property that they can fit together perfectly, edge-to-edge, without any spaces in between. This allows for a seamless tiling pattern that can cover a plane without leaving any gaps or overlaps.
On the other hand, triangles and pentagons cannot tessellate the plane without leaving gaps. Although there are tessellations possible with triangles and pentagons, they require a combination of different shapes to fill the plane without leaving gaps.
A circle, being a curved shape, cannot tessellate a plane without leaving gaps or overlaps. Circles cannot fit together perfectly in a regular pattern that covers the plane without any gaps.
Therefore, squares are the only shape from the ones you mentioned that can tessellate without leaving gaps.
