Question

Is it correct to say that ' There is no object with order of rotational symmetry as 0'.Justify this statement.

Answer 1

Is the minimum order of rotational symmetry 2?

Surely shapes with only the trivial case have order 1?

Eg (by my understanding)

F - has order one (or no rotational symmetry as some books would have it)

A non-square rectangle - Order two, we count both the 180 rotation position and the trivial case or orignial position.

What do other people teach? No rotational symmetry = order one or do you say minimum order of rotational symmetry is 2 and below that there is none.

Anybody wishing to lay down geometrical law out there or is it one of the eternal moot points?

Answer 2

Answer:

Yes it is correct to say that there is no object with 0°.

Step-by-step explanation:

Because the object is said to in rotation when it looks as the original object.
