One pair because opposite cross-section faces are parallel to each other.
A triangular prism has 9 parallel lines
2
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.

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.

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.
Each of the nine edges have another edge running parallel to them.
Each of the nine edges have another edge running parallel to them.
