A circle, rotated through an angle measuring any real value in the interval [0, 360 degrees) or [0, 2*pi radians) and remain symmetrical. The order of symmetries is therefore the continuum, C - a number that is uncountably infinite (as opposed to countably infinite). No other 2-dimensional shape can match that.

The perimeter of a circle measured from the centre is the same length no matter where the measurement is taken.
A circle or annulus. Each of its infinite number of diameters is an axis of symmetry. Plus there is the line through its centre and perpendicular to the plane of the circle.
Yup, assuming it's a perfect circle. I guess it kind of depends on the font, though...but for the most part, yes.
A circle is symmetric about ANY diameter. The number of possible diameters of the same circle is infinite. And on the same principle, a sphere will have lines of symmetry in every direction in 3 dimensions.
circle
a circle has infinite line of symmetry, if you spin it, it has still got infinite linesso yes it is symmetrical
Yes - most vases are cylindrical in shape (or a variation of). Therefore - they have rotational symmetry.

Rotational symmetry is when you turn or rotate a shape and it still looks the same. A circle is the most common answer. However, it you rotate a square about 90 degrees, it still looks the same, so it is considered rotational symmetry. Technically, any shape can have rotational symmetry because it you rotate it 360 degrees, it still looks the same.Definition of rotational symmetry:Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted. The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex. It can not be the same side or vertex.
It is a circle whose lines of symmetry are infinite
A circle has infinitely many.
A circle, since it has an infinite number of lines of symmetry
It has at most one.

A B C D E H K M U V W X Y * * * * * What? Most of these letters do not have rotational symmetry and so cannot have rotational AND line symmetry. Or did the meaning of AND change last night? The only upper case letters with both are H, I, O, X
Yes because it has infinite lines of symmetry.
