The Prime Meridian is the reference line. That's the meridian of longitude that joins the
north and south poles and passes through a mark on the floor of the transit room of the
Royal Observatory at Greenwich, a suburb of London. By international agreement, that
line is zero longitude. All others are measured east or west from it, from zero to 180°.

What are the reference point for latitude and longitude?
The latitude and longitude references are lines, not points. The reference for latitude is the line that forms a circle and consists of all points with zero latitude. That line is called the "equator". The reference for longitude is the line that forms a semi-circle and consists of all points with zero longitude. That line is called the "Prime Meridian".
A meridian is a line of what?
A meridian is a line of constant longitude.
What is meridian line of 0' longitude?
The "Prime Meridian" ... the one that passes through the Royal Observatory in Greenwich UK ... is the zero reference for longitude.
Difference between meridian and longitude?
The longitude of a point on earth is the angle, east or west, between that point and a certain reference line on the earth. If you take a globe or a map and draw a line through all the points that have exactly the same longitude, the line you get is the meridian of that longitude. The reference line is the meridian of zero longitude, called the "Prime Meridian". On that line are all the points on earth that have zero longitude. The line joins the north and south Poles, and passes through the Royal Observatory at Greenwich, a suburb of London.
When using latitude and longitude to find places on earth what do you use as your starting point?
The equator is the zero reference line for latitude, and the Prime Meridian is the one for longitude.
What is the name of the starting line for determining longitude?
prime meridian
