On the globe, parallels of latitude drawn at 1-degree intervals include 89 lines in the Northern Hemisphere (1°N to 89°N), 89 lines in the Southern Hemisphere (1°S to 89°S), and the Equator (0°), making a total of 89 + 89 + 1 = 179 latitude circles. (The 90° North and 90° South poles are geographic points rather than lines/circles).
