- Perpendicular and Parallel Edges and Faces
A sketch of a rectangular prism or a cube is looked at, and every edge or face perpendicular or parallel to a named one is written out. Four kinds appear, Relationship Between Edges and Relationship Between Faces, Relationship Between Edges and Faces and Relationship Between Faces and Edges, and since the answer need not be a single one, everything that fits is written as a set.

Anything answered as perpendicular touches the named edge or face somewhere. Anything answered as parallel, by contrast, meets it at no point at all. Sort by those two and neither question causes hesitation. Whether the very edge or face named in the question has crept into the answer is also worth looking at.
Features of Rectangular Prisms and Cubes viewed edges and faces by their counts and lengths. This lesson says how they connect in the two words perpendicular and parallel. Nets of Solids traces the same correspondences on the flat shape before assembly.
