To prove: ( \frac{1}{2} AC = BC )

Given: ( AB = BC ) (line segment AC with AB=BC)

Proof:

Since ( AB = BC ), ( AB + BC = 2BC )

Also, ( AB + BC = AC )

Thus, ( AC = 2BC )

Dividing both sides by 2:

( \frac{1}{2} AC = BC )

Hence proved.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
