Lines of longitude (meridians) run north/south and measure angular distance east and west of the prime meridian to a maximum of 180 degrees east or west.
Lines of latitude (parallels) measure angular distance from the equator. The maximum is 90 degrees north or south of the equator.
Because when you travel in longitude, you can go all the way around the Earth, 360 degrees, crossing new longitudes all the way . But when you travel in latitude, the farthest you can travel is from one pole to the other pole ... halfway around the Earth, 180 degrees. Once you reach the opposite pole, if you keep going farther, you're just crossing latitudes that you've already crossed once.
Because you must go all the way around the Earth in order to cross every possible longitude, but you only need to go half-way around it ... pole to pole ... in order to stand at every possible latitude. And by the way . . . there are an infinite number of longitudes, that cover a range of 360 degrees, and an infinite number of latitudes, that cover a range of 180 degrees.
Latitudes are parallel to the equator. Longitudes converge like elastics on a soccer ball.

I tried. Believe me, I tried. But I finally had to give up trying to figure out whether 90 and 45 are latitudes or longitudes, and if they're latitudes, whether they're north or south latitudes, and if they're longitudes, whether they're east or west longitudes.

They aren't, latitudes are.
There are 360 longitudes
Latitudes, the north/south coordinates.
