It is more than the sum of the lengths of the sides AB and AC.

It is equal to the difference of the lengths of the sides AB and AC.

It is equal to the sum of the lengths of the sides AB and AC.

It is less than the sum of the lengths of the sides AB and AC.

Answer 1

It's not more, so A is out.
If you were to add AB and AC, it would larger then BC. So C is out
It's not less, so D is out.

That leaves you with B. t is equal to the difference of the lengths of the sides AB and AC. ! :)
