90 degrees south latitude and ANY longitude is the South Pole.
90 degrees north, and 90 degrees south.
Latitude goes from zero degrees to 90 degrees north or south. The north pole is at 90 degrees north; the south pole is at 90 degrees south.
Latitudes range from zero to 90 degrees.The equator is the line of zero latitude.The north pole is 90 degrees north latitude.The south pole is 90 degrees south latitude.
Any number between zero and 90 degrees North, or between zero and 90 degrees South.
Latitudes range from zero to 90 degrees, north and south. Zero is at the equator, 90 north is the north pole, 90 south is the south pole, and that's as far away from the equator as you can get.
The greatest possible number of degrees of latitude is 90. Latitude is measured from the equator toward the North Pole or toward the South Pole. The equator is zero degrees of latitude. The North Pole is 90 degrees N, and the South Pole is 90 degrees S.
-- No location can have both a north coordinate and a south one (unless it's on the equator and its latitude is zero, so it makes no difference whether you call it zero north or zero south). -- And whatever the latitude of the location is, it can't be more than 90 degrees, either north or south. "90 degrees north" is the north pole, "90 degrees south" is the south pole, and no place is either more norther or more souther than those.
Latitude varies between 90 degrees North (the north pole), through zero (the equator) and down to 90 degrees South (the south pole). Some conventions use positive numbers for North, and negative numbers for South. Under this convention, latitude can vary from -90 to 90 degrees.
The cosine of 90 degrees is zero.
Latitude is measured from the equator (zero) to the North or South Pole (90 degrees). Going beyond 90 degrees, you would pass the North Pole (or South Pole).
The south pole lies at 90 degrees south.
the Prime meridian is a longitudinal line at 0 degrees and runs north and south. There is no 180 degrees below or above it. 180 degrees latitude doesn't exist. Latitudes range from 90 degrees south, at the south pole, through zero, at the equator, to 90 degrees north, at the north pole. There are no latitude numbers greater than 90.
