Problem 569

 

What does it means for an angle to be called a quadrant angle?

 

Solution:-

 

A quadrant angle is an angle in standard position in which the terminal side falls on an axis. For example, a 90, 180, 270, or 360 degree angle would all be considered a quadrant angle since there terminal sides fall on the positive y-axis, negative x-axis, negative y-axis, and positive x-axis, respectively.
