Where do the lines of latitude and longitude start?

The lines running north-south are known as lines of longitude. While lines of latitude run across a map east-west, the latitude indicates the north-south position of a point on earth. Lines of latitude start at 0 degrees at the equator and end at 90 degrees at the North and South Poles (for a total to 180 degrees of latitude).
