It is 360 degrees divided by the order of rotational symmetry.
A square.
Its to say its the MEASURE of the angle, instead of the angle itself
add 15 to it
An obtuse angle.
You don't rotate the angle, you rotate an object by that angle, for example if you had to rotate something 180o it would flip over.
A square.
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:
