Lines that run east to west another name is "parallels" Distance in degrees north or south of the Equator each degree of latitude is about 69 miles total of 90º North and another 90º South Facts About Latitude Where does it begin? the Equator an imaginary line that circles the Earth halfway between the North and South Poles Where does it end? the North and South Poles What is its unit of measurement? Degrees (minutes and seconds) Important lines of latitude The Equator = 0º The Tropic of Cancer = 23 1/2ºN The Tropic of Capricorn  = 23 1/2ºS The Arctic Circle = 66 1/2ºN The Antarctic Circle = 66 1/2ºS The North Pole = 90ºN The South Pole = 90ºS Add the Following Items to Your Glossary (16-18)   Latitude Equator Sextant
