Most maps will show latitude and longitude lines, if not, they're ALWAYS on a globe.
Latitude lines are parallel straight lines that run east-west, while longitude lines are not parallel to each other and appear curved when projected onto a map. Longitude lines converge at the poles and are widest at the equator.
The cylindrical map projection, such as the Mercator projection, shows all latitude and longitude lines as parallel. However, this projection distorts the size of land masses the further they are from the equator.
The parallel lines that run from east to west on a map show lines of longitude. Latitude specifies the north-south position of a point on the Earth's surface.
They are the horizontal lines on a map.
grid lines of longitude and latitude
On a normal map or atlas they are vertical.
Latitude lines are parallel straight lines that run east-west, while longitude lines are not parallel to each other and appear curved when projected onto a map. Longitude lines converge at the poles and are widest at the equator.
On a map, longitude lines go up and down, AKA vertically. Latitude lines are horizontal lines on a map.

The lines that intercept latitude lines are lines of longitude.

There can be various lines on a map, but the ones you are probably thinking of are 'latitude' and 'longitude'.
They are the horizontal lines on a map.

Parallel lines found on a map correspond to latitude.
