Question

Which of the following lines(of latitude or longitude) would represent by 180 longitude?

South Pole
Equator
Prime meridian
North Pole
International date line

Answer 1

International date line would represent by 180 longitude

Step-by-step explanation:

An "imaginary line of demarcation" on the earth’s surface that runs from the south pole to the north pole. It demarcates the one-day calendar change to the next. Through the centre of the pacific ocean, it passes with 180-degree longitude and halfway through the world from the Greenwich meridian.

Though in many cases the imaginary line of demarcation follows 180-degree meridian exactly. And at other places, the imaginary line of demarcation deviates east or west through the apex.
