In case its a triangle, there have 2b only 3 points na? also BD height is confusing me. D is given to make question tough and intresting. Also it gave a twist in the question. The way this question is designed, D is required and correctly signals the right angle as well.

BD is the Height to the Hypotenuse. In the right trinagle the non hypotenuse sides are the other heigts of the triangle. It is given in order to identify the Hypotenuse.

Since the triangle has ABC as a right triangle, the square of the triangle would be multiple of two non hypothenuse sides of the triangle divided by two. Statement ! just provides us with the information about the measurement of side AB Not sufficient. Hence, we know that 2) The product of the nonhypotenuse sides is equal to 24, which is multiple of sides AB and BC (reuqired sides) We can conclude that Statement 2 is sufficient to answer the question. Please, give me kudos, if you like my answer...

The point D is a misleading trap here. You don't need that information. Rt Triangle ABC  What's AB *BC  or one leg * hypotenuse Statement 1  not enough clearly Statement 2  product of two legs given, using the theorm hypotenuse^2 = leg1^2 + leg2^2 leg1 *leg2 = 24. Asked to find leg1*hypotenuse. From the above two equations it can easily be determined. Hence B is sufficient.

Since all points are distinct and BD is the height...D lies on AC and AC is hypotenueus. The right angle is formed at B. In all other scenarios, D equals either A/C
Answer: B

The triangle looks like this: BD being the height establishes that B must be across from the hypotenuse. This means AB and BA are the legs of the triangle.

ABC is a right triangle......the right angle can be any one out of A, B or C? Why does it have to be only B?

I just took this test. I had answered E.
I assumed that D should be a distinct pt. However, if the triangle is rightangled at A then the altitude BD can be drawn outside the triangular region ABC such that the BD will be parallel to AB or AC. In this case, the value of AB*BC will be 6*sqrt(52), which is different from the ans that we get if we assume that the triangle is right angled at B.
Please let me know if it I'm missing something.

Unless one of your points is on one of the straight lines, you have a quadrilateral and not a triangle.

1. AB=6 2. The product of the nonhypotenuse sides is equal to 24
could any one explain this? Can you check the question.. looks like something missing.

hi, I have a small question, If ABC froms a right angled triangle then the height should be either AB or BC or AC, then how did D come into the picture. I think this can be possible only when the point D coincides with any one of A, B or C. Could you explain if i got this wrong.
