a polygon
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.
circle
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
The only shape that has 4 lines of symmetry is a square.
No.
a circle has infiniti lines of symmetry
A square has exactly four lines of symmetry.
Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
yes
a polygon
If the figure is an image of a real heart, then there are no lines of symmetry. If it is an idealised heart, then 1.
