ABCD is a rectangle, where A, B, and C are the points (3,4), (1,K), and (4,-3) respectively.

Find the two possible values of K.

Anybody know how to solve this? Its probably something really basic, but I cant figure out how to work out K, I presume you have to get a quadraritic or something.

Regards.

since these triangles will form a pythagorus theorem, u can find the distances and get the answer ......

Um, possibly 3 or -4, not entirely sure, just drew a quick picture on the back of an envelope!
