Question

The equator blank latitude

Answer 1

I didn't really get the question but here is what I think you meant.

The equator is located at 0 degrees latitude. Because the Earth is widest at the equator, it is the longest line of latitude at 24,901.55 miles. Lines of latitude are imaginary lines that measure degrees north and south of the equator.(I type slow xd) 

Hope this helped! <3

Answer 2

The equator is 0 degrees, due to latitudinal lines radiating from it (the equator.)
