None of the following preserves the true shape of a plane figure except

  • A.the elevation of a figure inclined to both planes
  • B.a view on a plane parallel to the figure
  • C.a view on a plane perpendicular to the figure
  • D.the plan of a figure inclined to both planes

Answer: B

Correct answer: a view on a plane parallel to the figure

A figure is projected without foreshortening only onto a plane parallel to itself, so that view alone gives the true shape. A view on a perpendicular plane shows it edge on as a line, and both principal views of a figure inclined to both planes are foreshortened.
