One pair because opposite cross-section faces are parallel to each other.
A triangular prism has 9 parallel lines

Three.
It must have at least one.
A triangular prism has three planes of symmetry. Each plane passes through a vertex of the triangular base and divides the prism into two mirror-image halves. Additionally, there is one plane of symmetry that bisects the prism vertically through the midpoint of the triangular bases. This symmetry reflects the prism's geometric properties, making it a balanced shape.
A triangular prism has 9 parallel lines
there are two plane symmetry on triangular prism.
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.

Each of the nine edges have another edge running parallel to them.
Each of the nine edges have another edge running parallel to them.
There are 9 edges. It has three edges which are parallel to each other (along the length of the prism) AND it has three pairs of parallel edges - at the top and bottom of the prism.
In a general triangilar prism, none.In a right triangular prism, three pairs and one triplet.In a general triangular prism, none. In a right triangular prism, three pairs and one triplet.
