Answer:
The latitude at North pole is [tex]90^{\circ}[/tex]N
The latitude at south pole is [tex]90^{\circ}[/tex]S
Explanation:
Latitudes are used to measure the inclination angle of a point to the equator and also if a point is towards North or South. Its range is in between [tex]0^{\circ}[/tex] to [tex]90^{\circ}[/tex].
Longitudes are used to find whether a point is towards West or East of the Greenwich Meridian. Its range is in between [tex]0^{\circ}[/tex] to [tex]180^{\circ}[/tex].
Therefore, longitude is meaningless at the North and South Poles.
