Question

What is the order of rotational symmetry of a circle?

Answer 1

the order of rotational symmetry of a circle is 360.

Answer 2

The order of rotational symmetry of a circle is infinity.

• The order of a rotational symmetry of a shape is defined as the number of times that shape can be rotated so that it looks like the original shape it used to be.
• You can only rotate the figure up to a maximum of 360 degrees.
• The minimum order of symmetry of a shape is 1.
• For example the order of rotational symmetry is 2 because it will look alike at 180 degrees and 360 degrees.
• Similarly a circle will always look the same no matter the angle is, hence the order of rotational symmetry of a circle is infinity.
