Match the coordinate entry method with what it measures from.

1. Absolute   2. Relative   3. Polar

P. The previous point, as two offsets   Q. The fixed origin   R. The previous point, as a distance and angle

  • A.1-P, 2-Q, 3-R
  • B.1-Q, 2-R, 3-P
  • C.1-R, 2-P, 3-Q
  • D.1-Q, 2-P, 3-R

Answer: D

Correct answer: 1-Q, 2-P, 3-R

Three ways of naming a point. Absolute entry measures from the fixed origin. Relative entry measures from the previous point as two offsets. And polar entry measures from the previous point as a distance and an angle. The last two share their reference and differ only in how the step is described.
