Visually it doesn't make sense for an angle to be negative. However we often measure angles off of some axis, such as the x-axis, and positive angles go around counter-clockwise, while negative angles go around clockwise. Outside of the context of a Cartesian Coordinate system (x-y plane), negative angles don't generally make sense.

What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
Is a zero degree angle better than a positive or negative angle?
Better for what?
What is a line wxtending from the upper lift to the lower right has this type of slope?
The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.
Does a nonconvex polygon have exterior angles equal to 360?
No, but the sum of the exterior angles is 360 degrees. But remember that the exterior angle related to any reflex angle will be negative.No, but the sum of the exterior angles is 360 degrees.

What is the measure of the other two angles that are equal?
An angle plus an equal angle would be equal the first angle multiplied by 2, it cannot be equal to any exact measurement because angle measures are like numbers, they can go up to infinity, and down to negative infinity. The only thing I can tell you about the new angle is that it will be an even numbered angle.
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
What name is given to an angle below zero?
This is a negative angle.
What are positive and negative angle?
positive and negative angles of 87 degrees
Can reference angles be negative?
Certainly. A negative angle is simply clockwise instead of counterclockwise from the zero angle, but this is usually not indicated as such on a drawing.
Is a zero degree angle better than a positive or negative angle?
Better for what?
Is an angle be negative?
Yes. Sometimes in mathematics, it is useful to have negative angles. You can increase or decrease an angle by 360 degrees (or 2*pi radians) without changing the characteristics of the angle. Thus, for example, an angle of 30 degrees is equivalent to an angle of -330 degrees.
Can an angle be negative in trigonometry?
no because the only way degrees can be negative is in temperature.
Sin -0.5 is negative angle?
sin0.5
In a capacitor circuit load angle is?
Negative.
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.
Can angle measurements be negative?
Yes, although it may seem strange. Conventionally, on a Cartesian plane, angles are measured in an anticlockwise dirction, from the x-axis. Consequently, an angle in the clockwise direction could be considered a negative angle. It might be simpler to think of an angle of 359 degrees as one of -1 degrees, instead. Sometimes you need to subtract one angle from another and in that context, a negative measure for the angle is implicit.
Is zero degree an acute angle?
A non negative angle which is less than 90 degrees is an acute angle. So, Zero degree is an acute angle.
