Seems you have your ideas wrong here... Latitude is measured by degrees north and south of the equator. Longitude is measured east and west of the Greenwich meridian. (And that means 0 degrees is at Geenwich, England.) There is no such thing as 12 degrees east latitude. Please rethink your question and ask it a bit diferently.
latitude
The lines of latitude on a globe measure the distance east and west.
They are the lines of latitude, and they are also called parallels.
latitude
East-West circling the globe.
latitude
If a map or a globe has latitude 'lines' printed on it, they will point east-west.
The lines on the globe are not called "latitude", any more than the marks on a thermometer are called "temperature". The lines on the globe that mark intervals of latitude are called "parallels" of latitude.
The lines of LATITUDE run east-west around the globe and measure the angle north or south of the equator (which is 0° latitude). They are at 90° angles to the lines of LONGITUDE.
Parallels of latitude are numbered by degrees north or south of the equator. The equator is zero degrees, while the north pole is at 90N and the south pole at 90S. Depending on the scale of your map or the size of your globe, the printed lines of latitude may be every degree, every 5 degrees or every 15 degrees.
