The following are true of a cylinder:

• It has two parallel and congruent circular bases.


• Its lateral surface is "curved."


• It has no vertices.


• Parallel line segments connect corresponding points on the two parallel and congruent bases.


• If a plane intersects the cylinder and is parallel to the bases, the cross section is a circle and is congruent to each of the bases.


• The term "edge" describes the line segment formed where two faces meet. This term does not apply to cylinders.
