It is the axis of symmetry which is a line such that a object that is rotated at right angles to it becomes congruent to its original state before the angle of rotation reaches 360 degrees.
It has line symmetry (straight down the center) but not rotational symmetry.
Yes. Any equilateral shape can have both rotational and line symmetry.
No A rectangle has rotational symmetry as well
parallelogram * * * * * A parallelogram does have rotational symmetry (order 2).
Both.
The letters H and Z have both line symmetry and rotational symmetry
It has line symmetry (straight down the center) but not rotational symmetry.
A line has rotational symmetry of order 2.
A line has 180 degrees rotational symmetry.
F has no symetry : line or 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.
Yes. Any equilateral shape can have both rotational and line symmetry.

Line symmetry.
parallelogram * * * * * A parallelogram does have rotational symmetry (order 2).
Both.
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
