The upper portion of the figure shows the correspondence with the polar plane quadrants only when  r is positive. The lower part of the figure shows that when r is negative points are plotted in the diagonally opposite quadrant. 

1Step 1. Given information

The figure 

2Step 2. Significance of the given figure.

This given figure represents the position of the point in the polar plane in two different cases.

The upper portion of the figure represents the case when  when r is positive.

So the points to be plotted in the given quadrant.

The lower part of the figure represents the case when r is negative then  points are plotted in the diagonally opposite quadrant.
