Geometric borders

Geometric boundaries are formed by straight lines (such as lines of latitude or longitude), or occasionally arcs (Pennsylvania/Delaware), regardless of the physical and cultural features of the area. Such political boundaries are often found around the states that developed out of colonial holdings, such as in North America, Africa and the Middle East. The Canada–United States border follows the 49th parallel for roughly 2,175 miles (3,500 km) from Lake of the Woods (Ontario and Minnesota) west to the Pacific Ocean.
