What you see in the second image is a projection of the first, after a rotation. So treat it exactly like that. Meaning, you have 4 lines in mathbbR3. You know their equations. Furthermore, you have another 4 lines in mathbbR2 corresponding to the second image.
To solve, parameterize the family of possible 4 lines in mathbbR3 that project onto the 4 lines in mathbbR2. Find the matrix that takes the original 4 lines to generic quadruple in the mentioned family. Now write equations to ensure that matrix is actually a rotation. You should have enough information for there to be at most one quadruple that can actually be gotten from the original lines. If not, then your question has multiple answers.
