A plane perpendicular to the horizontal plane and inclined to the vertical plane has a horizontal trace that is

  • A.perpendicular to the reference line
  • B.coincident with the reference line
  • C.inclined to the reference line
  • D.parallel to the reference line

Answer: C

Correct answer: inclined to the reference line

A plane perpendicular to the horizontal plane cuts it in a definite line, and the direction of that line is the plane’s inclination to the vertical plane. So the horizontal trace is inclined to the reference line at exactly that angle, which is why the angle can be measured directly from the trace.
