Given two sets of polar coordinates that could be used to play the given point

 a.  (2.5, 300°)  and  (-2.5, 120°)

               b.  (4, 270°)    and   (-4, 90°)

Step-by-step explanation:

Polar coordinates are written as (r, θ)    where

In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)

You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)

                                                                           ↓

                                                                    (300 - 180)

In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)

You can also list the radius as -4 at angle 90° --> (-4, 90°)

                                                                      ↓

                                                                (270 - 180)
