A Parallel - because they are imaginary lines that run around the earth parallel to the equator
For map reading purposes, which includes dividing lines for nations such as Korea and Vietnam; a parallel is an imaginary man made line that circles the earth, designed in latitudes north and south of the equator. Used for (as) reference points when navigating.
