The heart does have both symmetries. it can be split through the middle and rotated 4 times to make rotational symmetry
A heart shape does not have rotational symmetry, as it cannot be rotated around a central point and look the same at multiple angles. Instead, it has bilateral symmetry, meaning it can be divided into two mirror-image halves along a vertical axis. Thus, while it lacks rotational symmetry, it has one line of symmetry.
No a Z doesn't have a rotational symmetry
A trapezoid has no rotational symmetry.
It has line symmetry (straight down the center) but not rotational symmetry.
