An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.
Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.

I believe that an octagon has 16 lines of symmetry.
None - it has rotational symmetry - not reflection symmetry.
Rotational symmetry is based on points of rotation not lines

how many lines of symmetry has an equilateral triangle
None.
None.
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).

None - it has rotational symmetry - not reflection symmetry.
None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
