How many rotational symmetries does a sphere has?
Infinitely many.
How many symmetry lines are there in a hexagon?
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).
How many rotational symmetries does a kite have?
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).
What is the rotational symmetry of an octagon?
Rotational symmetry means it will look the same after being rotated a certain amount. Let's assume that you mean a regular octagon where the sides are all equal in length and the angles are all the same (135 degrees). With such an octagon, if you rotate it one turn to the right (that's 45 degrees), it will look just the same. Rotate another 45° and it is still the same. You can do this 8 times so we say that a regular octagon has an order of rotational symmetry of 8.
What is the rotational symmetry of a rectangle?
It has rotational symmetry to the order of 2
