Assuming the question is about ROTATIONAL symmetry rather than rational symmetry, the answer is none.
triangle
A regular pentagon has rotational symmetry but does not have rational symmetry. Rational symmetry refers to the property of a shape that can be divided into equal parts by rotations that are fractions of a full rotation (e.g., 1/2, 1/3). Since a regular pentagon can only be rotated by 72 degrees (1/5 of a full rotation) to map onto itself, it does not exhibit rational symmetry.
none
yes
is a square a rational symmetry? is a square a rational symmetry?
None, since there is no such thing as rational symmetry.
Assuming the question is about ROTATIONAL symmetry rather than rational symmetry, the answer is none.
trust
if you mean rotational symmetry then yes, rotational symmetry of order 4

Yes the letter A has a vertical line of symmetry
no, letter N has no line symmetry.
No the letter "R" has no line of symmetry.
