Degrees, Minutes, Seconds:

One degree, denoted by 1°, is 1/360 of a complete rotation counter-clockwise. ( 1 rotation = 360° )
One minute, denoted by 1', is 1/60 of a degree (1° = 60' ).
One second, denoted by 1", is 1/60 of a minute ( 1' = 60" ).

The degree measure of q = x° if q is rotated counter-clockwise and q = -x° if q is rotated clockwise.
