What two quantities define a point in polar coordinate entry?

  • A.an angle and a radius of curvature
  • B.a distance and a layer name
  • C.a distance and an angle
  • D.two perpendicular distances

Answer: C

Correct answer: a distance and an angle

Polar entry gives the length of the step and the direction it runs in, which suits geometry described by bearings or by an included angle. The two methods are complementary: rectangular entry suits work laid out on a grid, and polar entry suits work laid out by angle.
