Yes, copies of a polygon can be used to tile a surface, provided the polygon is a suitable shape. Regular polygons, like squares and equilateral triangles, can easily tile a plane without gaps or overlaps. However, some irregular polygons can also tile surfaces, depending on their angles and side lengths. The key requirement for a polygon to tile a surface is that it can cover the area without leaving any spaces between the tiles.
