A kite has only one line of rotational symmetry, as it is only the same if it is tilted once. (back to its normal position).
Infinitely many.
a heart have no rotational symmetry!
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).
A quadrilateral with reflectional symmetry but not rotational symmetry would be a kite. A kite has two pairs of adjacent sides that are equal in length, and the diagonals of a kite are perpendicular to each other. When a kite is reflected across its line of symmetry, it will match up perfectly with its original position. However, if you try to rotate a kite by any degree, it will not match up with its original position, thus lacking rotational symmetry.
Rotational symmetry of order 1.
It has 8 rotational symmetry.
There is one line of symmetry in a kite
Infinitely many.
An ellipse has rotational symmetry of order 2.

yes, in fact it can have 6 rotational symmetries.
