Line or reflective symmetry is really a special case of rotational symmetry but from a different viewpoint.
In line symmetry imagine a line going north to south on the page. If you rotate an image out of the page around that line through 180 degrees you get a reflection.
For rotational symmetry imagine that same line being perpendicular to the page so that you see it as a dot. The image is then rotated around that dot.

Does z have rotational symmetry but no line symmetry?
The letters H and Z have both line symmetry and rotational symmetry
What does f have rotational symmetry or line symmetry or both or neither?
F has no symetry : line or rotational symmetry
Does a triangle have a line symmetry rotational symmetry or both?
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.
Can a figure have line symmetry and not rotational symmetry?
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
Does z have a line of symmetry?
It has a line of rotational symmetry - along the diagonal.
