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.
You can find lines of symmetry without tracing but tracing helps you get a better picture of it.
a circle has infiniti lines of symmetry
A square has exactly four lines 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.
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.
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
circle
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
A regular hexagon has six lines of symmetry. Lines of symmetry are imaginary lines where you can fold a figure or image and both halves are identical matches.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
