That's called the "prime meridian".
A circle has 360 degrees and a square has four 90 degree angles as does a rectangle.It's called complementary. A 90 degree angle is called supplementary.
This imaginary circle is called the prime meridian. it is an imaginary line that circles the globe vertically and is typically measured as beginning in Greenwich, England.
