All longitudes converge at the north and south poles.
at the Poles
Parallel lines, by definition, cannot meet. The lines of longitude meet at the Poles.
Lines of longitude meet at the North and South Poles.
All lines of longitude meet at the North and South Poles.

The poles
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
-- All lines of longitude meet at the north and south poles. -- No two lines of latitude ever meet or cross each other. -- Every line of longitude crosses every line of latitude. -- Every line of latitude crosses every line of longitude. -- There are an infinite number of each kind, so there are an infinite number of places where a line of longitude crosses a line of latitude. (That's kind of the whole idea of the system.)

All meridians of longitude converge at the north and south poles.
If you mean the longitude lines, as seen on a globe, they meet at the North Pole and at the South Pole.
The Lines of Longitude all meet at the Poles.
