To measure latitude, where should you place one point of a divider?

• A. The longitude line nearest the object
• B. The latitude line nearest the object
• C. The Equator
• D. The Prime Meridian

Answer: (B)

Latitude is defined by the horizontal lines that run east-west across a chart. To determine the object's latitude with a divider, you place one point on the latitude line that passes closest to the object's position. That line directly represents the object's north/south position, so using it as the anchor lets you read or transfer the exact latitude value on the chart. The other options refer to longitude or to a specific reference line (the Equator or Prime Meridian) and don’t provide the latitude of the object unless the object happens to lie on those specific lines.
