Are edges and sides the same thing?

Answer 1

It gets confusing. In a futile attempt to standardize terminology, use "sides" for 2d figures (the sides of a square), use "edges" for 3d figures (the edges of a prism) and use "faces" for 3d figures (the faces of a tetrahedron).

Answer 2

No they are not. In common usage, sides and faces are often used to mean the same thing. A six-sided die is actually one with six faces..

Answer 3

no
