Latitude

Definition

Latitude is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. It is measured in degrees, ranging from 0° at the Equator to 90° at the poles, and plays a crucial role in navigation, cartography, and astronomy. In Islamic astronomy, understanding latitude was essential for determining prayer times and the qibla, the direction Muslims face during prayer.
