    A polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. Key Terms. radius: A distance measured from the pole. angular coordinate: An angle measured from the polar axis, usually counter-clockwise.
