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.
Every latitude on the Earth is measured north or south from the Equator. The Equator is a line that marks the exact halfway point between the North Pole and the South Pole. The plane of the Equator is at 90 degrees to the Earth's rotational axis. The tropics are two other important parallels.
