The starting point for latitude is the equator. For longitude it is the prime meridian. Try and not get confused because some people think that it is the prime meridian for both but it is not. Hope this helps!
The answer is 0 degrees because latitude runs west to east/east to west and 0 degrees is the middle which ends up to the equator, which is 0 degrees latitude.
A starting line for longitude measurement is often called a Prime Meridian. Canada has many for various reasons and recognizes the Greenwich Meridian.

A Line of longitude is an invisible line going north to south on the earth. The main one is called the prime meridian.
The North and South Poles.

The International Date Line
-- Sweden ranges in longitude from 11° to 24.2° East. -- Greece ranges in longitude from 19.4° to 26.6° East. -- Zambia ranges in longitude from 22° to 33.7° East. So, any 'line' of longitude between 22° E and 24.2° E passes through all three of those countries. There are an infinite number of them.

Zero degrees longitude is the prime meridian, the line of longitude that passes through Greenwich, England.
equator
Yes it is. It is the starting point to measure degrees East or West.
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°.
Latitude is an angle measured north or south from the equator. Longitude is an angle measured east or west from the Prime Meridian

The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
The equator is the zero reference line for latitude, and the Prime Meridian is the one for longitude.

The major line of longitude located at 180 degrees longitude is the International Date Line.
