answer :

in quadrant notation and azimuthal notation, there are four quadrants that are defined as follows:

1. quadrant i: this quadrant is located in the upper right-hand corner and contains angles with values between 0 and 90 degrees. in this quadrant, both the x- and y-coordinates are positive.

2. quadrant ii: this quadrant is located in the upper left-hand corner and contains angles with values between 90 and 180 degrees. in this quadrant, the x-coordinate is negative and the y-coordinate is positive.

3. quadrant iii: this quadrant is located in the lower left-hand corner and contains angles with values between 180 and 270 degrees. in this quadrant, both the x- and y-coordinates are negative.

4. quadrant iv: this quadrant is located in the lower right-hand corner and contains angles with values between 270 and 360 degrees (or 0 and -90 degrees). in this quadrant, the x-coordinate is positive and the y-coordinate is negative.

quadrant notation is commonly used to represent angles in the cartesian coordinate system, while azimuthal notation is commonly used in polar coordinates.
