Everything north of the equator is known as the Northern Hemisphere and everything south of the equator is known as the Southern Hemisphere. Lines of latitude are called parallels and in total there are

**180**degrees of latitude. The distance between each degree of latitude is about**69**miles (**110**kilometers).Beside this, what are the 5 main parallels of latitude?

The

**five**major**parallels of latitudes**from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle. On a maps where the orientation of the map is either due north or due south,**latitude**appears as horizontal lines.Can you have parallel curves?

As for

**parallel**lines, a normal line to a**curve**is also normal to its parallels. When**parallel curves**are constructed they**will**have cusps when the distance from the**curve**matches the radius of curvature. These are the points where the**curve**touches the evolute.How many tangents can a circle have?

Exactly

**0 tangents**can be drawn through a circle. A tangent intersects a circle in only one point so it does not actually enter the area of the circle. An infinite number of tangents to a given circle can be drawn since their is no limit to the points a tangent could intersect.
