no because the only way degrees can be negative is in temperature.
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.
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.
A non negative angle which is less than 90 degrees is an acute angle. So, Zero degree is an acute angle.
The helix angle of reamer is negative because to make the reamer more regid so that the reamer can withstand the vibration during reaming
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.
This is a negative angle.
positive and negative angles of 87 degrees
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.
Better for what?
