Use tracing paper.
Alternatively, try to find a point that is the same distance from an end point of lines u and v, and the same distance from the other end points of u and v.

Trevor P, Shropshire SY4:
Centre C takes the right hand end of line u to the bottom end of line v.
So I looked for a centre that takes the right hand end of u to the TOP end of v.
Lots of points can do this, for example (5, 2), (4, 3), (3, 4), (2, 5).
However, the only other point that takes ALL of line u onto v is (3, 4).
