Cartesian quadrants

In the Cartesian coordinate system, the four quadrants are defined as follows:
Quadrant I - (top right): Angles between 0^◦ and 90^◦
Quadrant II - (top left): Angles between 90^◦ and 180^◦
Quadrant III - (bottom left): Angles between 180^◦ and 270^◦
Quadrant IV - (bottom right): Angles between 270^◦ and 360^◦

Check that the angle fits according to quadrant's definition
