What do you call the imaginary lines that divide the earth into squares giving a precise number location for a place ? ?

Latitude and Longitude are the imaginary lines that divide the earth into squares giving a precise number location for a place.

Explanation:

The horizontal imaginary line that divides Earth into 'North and South poles' is called Latitude. The vertical imaginary line that divides Earth into 'East and West hemispheres' is called Longitude. Together Latitude and Longitude form the Earth's geographical coordinates which represent the 'angular distance of any location' on Earth from its center. The four imaginary lines on the globe are Equator, tropic of Cancer, Tropic of Capricorn, Prime Meridian. Only one continent Africa has all the 'four imaginary lines' passing through it.
