Given n^2 = 5n, the assertion says that n is necessarily equal to 5.

Solving n^2 = 5n gives:

n^2 – 5n = 0

n(n – 5) = 0.

As well as n = 5, n = 0 meets the requirement, and that is your counterexample.

If point G is on lineAB then G is on lineBA.

I do not see any counterexample for this. Line AB and line BA are the same line.
