In navigation, which term is synonymous with angles measured from the equator?

In navigation, the term synonymous with angles measured from the equator is latitude. Latitude refers to the imaginary lines that run parallel to the equator and are used to specify the north-south position of a point on the Earth’s surface. Each degree of latitude represents an angle that indicates how far north or south a location is from the equator, which has a latitude of 0 degrees.

Understanding latitude is fundamental for navigation as it helps pilots, sailors, and others determine their position relative to the equator, which is crucial for route planning and ensuring safe passage. This use of angles allows for a precise geographical reference system, enabling travel and exploration across the globe.

Other terms do not have the same specific meaning: coordinates encompass both latitude and longitude, which together define a location; meridians refer to the lines of longitude that run from pole to pole; and northings describe the distance traveled north in navigation, rather than an angular measurement from the equator.
