A figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.
Line
Many figures. For example, an ellipse.
You turn it a quarter to see if it still has a line of symmetry.
A line has 180 degrees rotational symmetry.
yes
The letters H and Z have both line symmetry and rotational symmetry
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.
F has no symetry : line or rotational symmetry
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
z
Both.
Yes. Any equilateral shape can have both rotational and line symmetry.

Only an equilateral triangle has rotational symmetry.
