Which of the following two-dimensional shapes can be rotated to create a cylinder?

triangle
square
circle
ellipse

A rectangle works as well, and it is the more general answer. If you were to rotate either figure along an axis parallel to one of the sides, then you will effectively create a revolving door motion. This sweeps out the 3D shape of a cylinder.

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
