Let A(1, 2), B (3,4), C( x, y) be points such that (x- 1) (x-3) +(y-2) (y-4)=0. Area of triangle ABC=1.
maximum number of positions of C in the xy plane is
(a) 2
(b) 4
(c) 8
(d) None of these
I have tried using the staircase formula which gives me something like x-y=2. Therefore I see only two possibilities: (1,3) & (2,4) which are in accordance with the equation given. So, acc to me, ans is a. But according to the book,the answer is b.
Any help would be appreciated. Thanx in advance...
