Best ResponseYou've already chosen the best response.0Which of these could be a step to prove that BC^2 = AB^2 + AC^2? By distribution, AC^2 plus AB^2 = BC multiplied by the quantity DC plus AB. By distribution, AC^2 plus AB^2 = BC multiplied by the quantity DC plus BD. By distribution, AC^2 plus AD^2 = BC multiplied by the quantity DC plus AB. By distribution, AC^2 plus AD^2 = BC multiplied by the quantity DC plus BD.

Best ResponseYou've already chosen the best response.1the question is pretty nebulous. But it looks like they are using the idea that segment BC is the same as BD+DC so BC^2 = BC * BC = BC* (BD+DC)

Best ResponseYou've already chosen the best response.0so that narrows it down to answers D and B, right?

Best ResponseYou've already chosen the best response.1also, it seems they are using AB^2 + AC^2 = BC^2

Best ResponseYou've already chosen the best response.1so we have AB^2 + AC^2 = BC* (BD+DC) I'm not sure how this is a proof, but it's true.
