Keep one end of the line at the center of Earth and raise the other end from the equatorial plane (It is a convention that "up" on a map or globe is north.) along the edge of the sphere. If you raise it 45°, you are at 45 degrees North latitude. Wisconsin is at that latitude. Moving around the globe tracing an imaginary circle at this angle you will also find South Dakota, Mongolia, France, and Maine. If you raise the end of the line to 90 degrees North (straight up from the center) you are at the North Pole. There is no line here. | Keep one end of the line at the center of Earth and raise the other end from the equatorial plane (It is a convention that "up" on a map or globe is north.) along the edge of the sphere.
