Final answer:
The letter "N" has neither line symmetry nor rotational symmetry; no line can divide it into mirror-image halves, and it cannot be rotated less than 360 degrees and retain the same appearance.
Step-by-step explanation:
When we describe the letter "N" in terms of rotational and line symmetry, we need to analyze the shape for these types of symmetries. A shape has line symmetry if one can draw a line through it and the shape appears to be the same on both sides of the line. The letter "N" has no line symmetry, as no such line exists that divides it into two mirror-image halves. Furthermore, a shape has rotational symmetry if it can be rotated (less than a full circle) about a central point and still looks the same. The letter "N" does not have rotational symmetry because it cannot be turned to any angle less than 360 degrees (a full rotation) and still look the same.
