There is one line of symmetry in a kite

An ellipse has rotational symmetry of order 2.
yes, in fact it can have 6 rotational symmetries.
A seven-pointed star has seven rotational symmetries. This means it can be rotated in increments of ( \frac{360^\circ}{7} ) and still appear unchanged. Each of these rotations corresponds to one of the seven points of the star. Therefore, the total number of rotational symmetries is equal to the number of points.
A regular decagon, which has 10 equal sides and angles, has 10 rotational symmetries. These symmetries correspond to the decagon being rotated by multiples of (36^\circ) (360° divided by 10), including the identity rotation (0°). Therefore, the decagon can be rotated to match its original position in 10 different orientations.
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.
