Which direction do you measure an angle?
Unfortunately there is no consistent direction: it depends on the context. If dealing with bearings (eg navigation) North is 000 degrees and the angle is measured in the clockwise direction starting from the Northward direction. In the context of coordinate geometry, particularly if working with polar coordinates, angles are measured in the anti-clockwise direction, starting with the x-axis (pointing East) as 0 degrees. Generally speaking, though, angles may be measured in any direction.
Why do quadrants on a coordinate plane go counter clockwise?
Because angles, which start at 0 degrees, travel in that direction. When an angle is at 0 degrees, it is located to the right of the y-axis, and on the x-axis. As the degrees grow larger, the angle unfolds to the left, or counter-clockwise.
Which way is clockwise on a circle?
Moving in a clockwise direction on a circle is the equivalent to moving from right to left. This is also the direction used to tighten bolts.
what is a horizontal angle measured clockwise from a north base line?
An Azimuth
What direction is 45 degrees clockwise from due east?
North East
What does it mean when an angle is negative?
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
When is an angle positive?
An angle is positive when it is measured in a counter-clockwise direction. It is negative when it is measured in a clock-wise direction.
What direction of rotation produces a negative measure of an angle?
Clockwise.
What is the northeast direction of an angle from eastward?
45 degrees clockwise.
What is the Horizontal angle of a bearing clockwise from a standard direction called?
azimuth
Is angle scalar or vector?
Almost all of us would say that angle is a scalar quantity. But the beauty is that angle is a vector quantity. Now the question arises. Where will be the direction? As we measure the angle in a plane in counter clockwise direction, then direction of angle vector will be perpendicular to the plane and coming out of the surface. If the angle is measured in clockwise then vector would go into the surface normally. As angle becomes vector then angular velocity w = @/t also becomes a vector.

Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
Positive and negative angles?
In the Cartesian plane, an angle is measured in the anti-clockwise direction from the x-axis. A negative angle is measured in the clockwise direction from the x-axis. However, an angle is effectively the same if you add or subtract 360 degrees. So, if you are faced with a negative angle just keep adding 360 degrees until you have a positive value.

Is there a positive or a negative angle?
Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.
What angle is constructed in surveying between north-south line through the observer to any point or projected on?
The angle is called the azimuth angle. It represents the direction of the point or projected line from the observer in relation to the north-south line. It is measured clockwise from the north direction.
