    What do you think?
    The answer for a rectangular prism would be yes.

    PS: I assume that we can discount shining the beam down the length of the prism.

    Not a rectangular prism , a triangular prism with angle of prism = 60degrees .

    Yes I know you asked about a triangular prism. My reference to a rectangular prism was a hint.
