An angle is commonly given an arithmetic value which describes its size. To specify its this value, an angle is drawn in a standard position on a coordinate system, with its vertex at the center and one side, called the initial side, along the x axis. The value of the angle then represents the amount of rotation needed to get from the initial side to the other side, called the terminal side. The direction of rotation indicates the sign of the angle. Traditionally, a counterclockwise rotation gives a positive value and a clockwise rotation gives a negative value. The three terms which are typically used to express the value of an angle include revolutions, degrees, or radians.
There are several different units in use for measuring angles.
-- Scientists and engineers use radians most commonly.
1 full circle = (2 pi) radians
-- Non-scientists and non-engineers use degrees most commonly.
1 full circle = 360 degrees.
-- Other units include
. . . turn = 360 degrees
. . . quadrant = 90 degrees
. . . astronomical hour angle = 15 degrees
. . . navigation point = 1/32 of a turn
. . . binary radian = 1/256 of a turn
. . . grad = 1/400 of a turn
. . . minute of arc = 1/60 degree
. . . second of arc = 1/60 minute
degrees and radians.
degrees: a number that wraps from 0 to 360 degrees
radians: a number that wraps from 0 to 2pi degrees
In trigonometry and calculus, you'll probably use radians, of which there are 2(pi) to a complete circle.
There's also gradians, where there are 400 to a circle.
Degrees minutes and seconds
centimeters
the unit is called ( i think ) geomatry!? LOLHAHAHAHAHAHAHAHAHA
The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.
Arc degrees, minutes and seconds are the units of angular measurement.
A solid angle, measured from a vertex, is the ratio between the area subtended by the angle at the vertex and the the square of the distance to the vertex. The unit of measurement is the stradian.
the unit used to measure angle is degree. It is also measured in radians.

Usually an angle is measured in degrees or radians.

it measures the angle (of something). The unit is degrees.

Latitude and longitude are angles, and can be expressed in any unit of angle measure. Degrees are quite popular.

Measure 3 of any unit on one of the sides that you suppose have a right angle. Measure 4 of the same unit an the oher side you suppose has a right angle. the distance between the marks you made should mbe 5 if it is a right angle
