Transcribed Image Text:Consider the given graphs:
Ug
U₂
16
Us
U₂
Us
Vs
V7
V₁
V6
V₂
V₂
V₂
G
H
Click and drag the statements in correct order either to show that these graphs are not isomorphic or to find an isomorphism between
them using paths.
Having thus been led to the only possible isomorphism, check that the 12 edges of G
do not correspond to the 12 edges of H; hence the two graphs are not isomorphic.
So try to construct an isomorphism that matches them, say u₁ → V₂ and us → V6.
Proceeding along similar lines, complete the bijection with us Va, UgV7,
and U> → Vs.
Now u, is adjacent to uz and us, and v₂ is adjacent to vi and v), so u₂v and us V3
Since us is the other vertex adjacent to us and v4 is the other vertex adjacent to
V3, U4 V4.
Having thus been led to the only possible isomorphism, check that the 12 edges of G
exactly correspond to the 12 edges of H, and the two graphs are isomorphic.
