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.
Yes, a regular n-gon has n reflectional symmetries and n rotational symmetries. The n reflectional symmetries correspond to the lines of symmetry that can be drawn through each vertex and the midpoint of the opposite side. The n rotational symmetries arise from the ability to rotate the n-gon by multiples of ( \frac{360^\circ}{n} ), returning it to an equivalent position. Thus, both types of symmetry are equal to n.
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.
