Which of these could be a step to prove that BC^2 = AB^2 + AC^2?
Options:
1. By distrubtion, AC^2 plus AB^2 = BC multiplied by the quantity DC plus AB.
2. By distrubtion, AC^2 plus AB^2 = BC multiplied by the quantity DC plus BD.
3. By distrubtion, AC^2 plus AD^2 = BC multiplied by the quantity DC plus AB.
4. By distrubtion, AC^2 plus AD^2 = BC multiplied by the quantity DC plus BD.
