I have three homes H1, H2, H3 (see fig) and three things water W,
light L and gas G (see fig).
H1 H2 H3
W L G
I want to append W, L, G with each homes (H1, H2, H3), but it's one
condition: lines couldn't intersect. My questions:
1) Is it possible?
2) How to prove similar thing using graph theory?
.
