Let the third vertex of a triangle be C (h,k).

Other two vertices are A and B.

that is let, (a,b1) and (a, b1+a) respectively.

Area is given therfore,

a^2 = det( | a b1 1|

|a b1+a 1|

|h k 1| )................(1)

Then apply the distance formulae using coordinates of the triangle ABC with a as a constant distance b/w them. From there U would get again some other eqns.
