We're not sure what the question is getting at. Every meridian of constant longitude
intersects every parallel of constant latitude, and vice versa.

They intersect, yes.

You find the lines of latitude and longitude and find the place that they intersect, which is your location.
The two tropics are lines of latitude at 23°26′13.0″ North and South of the Equator and they intersect all lines of longitude.
Every line of longitude intersects with every line of latitude and vic-versa.
No, lines of latitude do not intersect.
Every line of constant latitude intersects every possible longitude, and vice-versa.
A meridian of longitude and a parallel of latitude are perpendicular at their intersection, forming a right angle.
So as to create a particular location on the grid where they intersect.
Lines of Latitude encircle the Earth horizontally, and are parallel to the Equator. Lines of Latitude are intercepted by Lines of Longitude. Lines of Longitude run vertically from the North Pole to the South Pole. The Prime Meridian is zero longitude and passes through the Greenwich Observatory, Greenwich, London, England.
