A 90 degree rotation is a quarter of a turn.
A degree is a measure of rotation, with 360 degrees representing a complete rotation returning to the starting point.
A Full rotation
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
360 degrees.
A 90 degree rotation is a quarter of a turn.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
A degree is a measure of rotation, with 360 degrees representing a complete rotation returning to the starting point.
the degree of a rotaiton of a star is 37 degrees

A 180 degree rotation between front and back is normal for US coins.
Answer: 130 degrees. 360x4=1440 degrees. So each time we have 360 degree rotation, we end up where we started. The rotation will be 1575-1440=130 degrees.
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
The effect of the rotation is the same as that of a 90 degree clockwise rotation. In matrix notation, it is equivalent to [post-]multiplication by the 2x2 matrix: { 0 1 } {-1 0 }
