How does an oblique cut alter the development of a cylinder?

  • A.the top edge becomes a curve while the base stays straight
  • B.the base edge becomes a curve while the top stays straight
  • C.both edges become curves of the same shape
  • D.the pattern becomes a sector rather than a rectangle

Answer: A

Each generator is cut at a different height, so the ends of the erected generators trace a curve across the top of the rectangle. The base circle is untouched, so the stretch-out line remains straight and the same length as before.
