Answer:
Lines of latitude start at 0 degrees at the equator and end at 90 degrees at the North and South Poles (for a total to 180 degrees of latitude).
Explanation:
There are 90° of latitude in each of the northern and southern hemispheres, ranging from 0° at the equator to 90° at the pole. The number of latitudes into which each range of 90° can be subdivided is virtually infinite.
