Use a protractor to measure that angle from a horizontal line. Look at where the angle line is on the Cartesian coordinate plane.
Explanation:
The “quadrants” start in the positive-positive x-y quarter of the Cartesian plane and progress clockwise around it. The respective degree boundaries are I: 0-90, II: 90-180, III: 180-270, IV: 270-360.
