The letters: I O H X o x all exhibit bilateral symmetry and rotational symmetry, with O and X exhibiting it in both upper and lower case.
Both.
Only an equilateral triangle has rotational symmetry.
Yes. Any equilateral shape can have both rotational and line symmetry.

The letters H and Z have both line symmetry and rotational symmetry
A B C D E H K M U V W X Y * * * * * What? Most of these letters do not have rotational symmetry and so cannot have rotational AND line symmetry. Or did the meaning of AND change last night? The only upper case letters with both are H, I, O, X
The letters: I O H X o x all exhibit bilateral symmetry and rotational symmetry, with O and X exhibiting it in both upper and lower case.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
Both.
16 letters have line symmetry: A, B, C, D, E, H, I, K, M, O, T, U, V, W, X, Y 6 letters have rotational symmetry: H, I, N, O, S, X, Z 4 letters have both: H, I, O, X
F has no symetry : line or rotational symmetry
Only an equilateral triangle has rotational symmetry.
Yes it does. A regular hexagon will have both rotational and reflectional symmetry about its centre.
Yes. Any equilateral shape can have both rotational and line symmetry.
It has both because it has 5 lines of symmetry and rotational symmetry to the order of 5
