What is the unit measure of an angle?

Answer 1

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.

Answer 2

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

Answer 3

The exact measure of an angle is degree . Because angles can be measures cannot be measured by a scale because it is special kind of shape with 2 rays fro the vertex . He lonley space can be measured by degree.

Answer 4

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.
