591Find 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!Upvote·0· Reply ·2014-03-27 21:15:00
