The letter U has rotational symmetry of order 1 because it looks the same after a 180-degree rotation.
The letter H has a rotational symmetry of order 2, meaning it looks the same after a 180-degree rotation.
yes, it has a rotational symmetry of 180 degrees, and of course 360. like if you flipped it upside down, then put it on top of the other one it would look the same. just not a lowercase.
Yes, it is possible to have a shape that has a line of symmetry but does not have rotational symmetry. An example is the letter "K", which has a vertical line of symmetry but cannot be rotated to match its original orientation.

H
There are 10 letters in the alphabet that achieve rotational symmetry when displayed in their capital form. These letters: A, H, I, M, O, U, V, W, X, and Y.
Yes, the capital letter N has rotational symmetry but no lines of symmetry:
S
letter o and x
None.
No, but the spokes on a bicycle do.
None.
None.
Two.
2
There is only one capital letter: O.
