Data Sufficiency

If distinct points A, B, C , and D form a right triangle ABC with a height BD , what is the value of AB times BC ?

1) AB=6
2) The product of the non-hypotenuse sides is equal to 24

[spoiler]OA is B but I don't get how !![/spoiler]

right triangle ABC with a height BD. This information tells us that the right angle is at B. This is because if the right angle is at A or C, then BD cannot be the height. The Line from B to the right angle will itself be the height.

So the only way a distinct point D can become the height is if the right angle is at B.

1) Not sufficient. AB is given but no BC.
2) Product of two non hyp sides: angle is at B. So non hyp sides are AB and BC. Sufficient.

All the best for your test.
Take it easy. Thats the most important thing on this test. Learnt it the hard way.
