why latitudes and longitudes expressed in angles?

Answer 1

The latitude of a place is the angle between the equator and the place, as seen from the center of the earth.

The longitude of a place is the angel between the greenwich meridian and the place, as seen from the center of the earth. (The Greenwich meridian is a line from the north pole to the south pole that goes through Greenwich, England).

Using angles is the only way to define coordinates on a sphere.

Answer 2

Uh, sorry to burst your bubble, but latitudes and longitudes are not expressed in angles at all. They are expressed in DEGREES. A degree is simply a value (a number) that shows how large something is. The larger the degree, the larger the number, which means the further away something is from something else.

An ANGLE is a measurement of how far apart two straight lines from the same starting point (sometimes called rays, or vectors) are separated from each other. These are also measured in degrees, but they are not the same. A degree is the MEASURE of an angle in geometry, and a degree is the MEASURE of geography - how far a certain location on a globe is located from somewhere else.

Make sense?

Answer 3

Because they are angles !

The Earth is a sphere (I know that a huge percentage of American do not know this, but believe me here).

Angle between equator and your place is the latitude.
Angle between Greenwich big circle and your place is your longitude.

Answer 4

The map of the world is divided into grids or squares and the location of any point on the map is a point on the grid defined as a degree from the equator and the prime meridian. I think?

Answer 5

It's really the only way to describe positions on a sphere. You were aware that the Earth is not flat... right?

Answer 6

they are measured in degrees, minutes, and seconds....... not in angles. Didn't you go to school
