Question

How many lines of latitude are there?

Answer 1

By counting each whole degree of latitude from the equator to the North and South Poles, we get a total of 181 lines. 

• Northern Hemisphere: 90 lines (from 1°N to 90°N).
• Southern Hemisphere: 90 lines (from 1°S to 90°S).
• Equator: The starting line at 0° latitude

90 +  + 90 + 1 = 181
