A triangular prism has 2 parallel faces, which are the triangular bases of the prism. Additionally, the lateral faces of a triangular prism are parallelograms, but they are not parallel to each other. Therefore, the total number of parallel faces in a triangular prism is 2.
5 pairs of parallel lines, plus a set of 5 parallels.
