Match the resting position with the base's relation to the horizontal plane.

1. Resting on its base   2. Resting on a base edge   3. Resting on a base corner

P. Inclined, touching at one point   Q. Parallel to the plane   R. Inclined, touching along a line

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

Answer: D

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

The three resting positions differ in how much of the base touches the plane. On its base the whole face is in contact, so the base is parallel to the horizontal plane. On an edge the contact is along a line, so the base is inclined. On a corner the contact is at a single point, and the base is inclined more steeply still.
