1. The problem statement, all variables and given/known data

Two 4-vectors are given by A = (5,4,3,0) and B = (5,5,0,0). I have to find out, which type of transformation comes out when transforming A over in B.

3. The attempt at a solution

I don't even think I understand the question. Can you give me a hint?

1) The time coordinates of the two 4-vectors are the same.

2) The lengths of the spatial 3-vectors are the same.

This means that you're looking for a spatial transformation that preserves spatial length.
