Can {f, h} ever be in an MST? Prove it:

Back

Can {f, h} ever be in an MST? Prove it:

No, because it's the heaviest edge in the cycle.
If there was an MST containing it, we could remove it and replace it by another edge in the cycle.
Then we preserve the tree property yet it's weight is strictly lower.
