SUMMARY
Longitudinal lines are defined as being perpendicular to the equator due to the spherical coordinate system used in geography. This perpendicularity ensures that the infinite number of longitudinal lines converge at the poles, maintaining the integrity of Earth's circumference. Without this perpendicular relationship, the mathematical representation of Earth's surface would be inconsistent and inaccurate.
