Subject: Using two-dimensional coordinates

When working in two dimensions, you specify points on the xy plane. You can spec­ify any point as an absolute coordinate (or Cartesian coordinate), using the exact x-coordinate and y-coordinate locations in relation to the origin (the 0,0 coordinate point at which the two axes intersect), or as a relative coordinate in relation to the pre­vious point. You can also specify points using relative or absolute polar coordinates, which locate a point using a distance and an angle.
