Question from Christa:

What do all prisms have in common?

Hi Christa,

The definition of a prism is

a geometric solid with two bases that are congruent, parallel polygons and all other faces are parallelograms. It is referred to as a right prism if the faces are rectangles. A prisms is named according to the shape of its bases. e.g. triangular prism

Hence every prism has parallel polygonal bases and faces that are parallelograms.
