In the diagram at right, points are plotted on a Cartesian grid. What are the polar coordinates of these points?

Each point should be written in the form , where is the distance from the point to the origin and is the angle of rotation measured counterclockwise from the positive -axis.

For points and , draw a segment from the point to the origin. Use the Pythagorean Theorem to determine r and inverse tangent to determine .
