Find the mid point and length of the diagonal with the vertices given and slope of the other diagonal and hence apply parametric form for the other diagonal

  • Rajiv Agarwal Another lengthier approach is by generating 4 equations. Let the co-ordinates by (x1,y1) & (x2,y2). (x1+x2)/2 = 2 (y1+y2)/2 = 3/2 (y2-y1)/(x2-x1) = -(2/5) (as this line is perpendicular to the given diagonal) and (x2-x1)^2+(y2-y1)^2 = 29 This is lengthy. Akshay's method is the preferred one!
