In the Transverse Mercator projection, distances are measured along which line?

In Transverse Mercator, the cylinder is wrapped so it is tangent to the Earth along a single meridian, called the central meridian. That meridian becomes the line of true scale, so distances measured along it on the map match real ground distances. Distortion grows as you move away from this line, which is why the central meridian is the only line where distances are preserved. The other lines, such as the equator or other meridians, don’t have true scale in this projection.
