Colloquially, it means to give it a one quarter turn. Imagine taking a dial that currently points upwards, and rotating it to point rightward. That is a 90° rotation. Similarly, the amount by which the minute hand in an analog clock moves in fifteen minutes should be 90°.
If you are looking to do this mathematically, the easiest way is to use a rotation matrix. In this case, you are rotating around the point 0, 0.

How do you rotate a figure 90 degrees counter clockwise about the origin?
You have to switch the x and y coordinates and multiply your new x coordinate by -1. You can also dram the point and rotate your paper physically by 90 degrees. Example: Your Coordinates: (3,8) New Coordinates: (-8,3) (3,8) ---> (8,3) ---> (-8,3) Another Ex: (-7,-1) --> (-1,-7) --> (1,-7)
