A full turn of 360degree is not used to describe rotational symmetry. Why not?

'16.3.22 11:07 PM (157.160.xxx.70)A shape has Rotational Symmetry when it still looks the same after a rotation.
How many times it matches when we go once around is called the Order.
Is there Rotational Symmetry of Order 1 ?
Not really! If a shape only matches itself once as we go around (ie it matches itself after one full rotation) there is really no symmetry at all, because the word "Symmetry" comes from syn- together and metron measure, and there can't be "together" if there is just one thing.2. 아줌마
