Yes. Any equilateral shape can have both rotational and line symmetry.
A line segment would have rotational symmetry.
The letters S, N, Z, for example.
A triangle........I think
Parrallelogram (it has rotational symmetry but no lines of symmetry)

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.
How about an isosceles trapezoid
The letters S, N, Z, for example.

Parrallelogram (it has rotational symmetry but no lines of symmetry)
The letters H and Z have both line symmetry and rotational symmetry
A shape does NOT need to have line symmetry in order to have rotational symmetry.For example, the letters N, Z and S can be rotated 180° to show symmetry, but none of these show line symmetry.When the folded part Line of Symmetry. Here I have folded a rectangle one way, and it didn't work.
It has line symmetry (straight down the center) but not rotational symmetry.
A line has rotational symmetry of order 2.
