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.
To find the smallest angle of rotational symmetry for a figure, divide 360 degrees by the number of rotational symmetries of the figure. The result will give you the smallest angle of rotational symmetry.
