Lines of latitude are measured in degrees north or south of the Equator, 0Â° latitude. In order to more easily understand how this angle is measured it is best to imagine that the Earth has been sliced in half along a great circle. The line connecting the North and South Poles is the Earth's axis of rotation. This is perpendicular, or at 90Â°, to the Equator. At the surface of the Earth, at a given latitude, draw a line from that location to the center of the Earth. The angle between this line and the Equator is the latitude measurement.
The equator is zero degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south, and in between is in between. Parallels, otherwise known as latitude lines, are lines that run across the Earth from east to west at a constant latitude. Everywhere on a parallel must have the same latitude. Your latitude can be calculated by measuring the angle of the sun. At the middle of the day on the equinox (when day and night are the same length) the angle of the sun below an upright line (a line straight up above your head) tells you your latitude.
