Hi HSN KMR!!!!


        IF you observe,(-2,1) is one point on the diagonal,but (3,2) isnt.


Now,try to find the point on the diagonal which is at a distance 6 from the point (3,2)


so,consider the poinr ro be (x,-(1+x)) and its dist from (3,2) is 6


so,use distance formula and u will get the third point and thus the slope of a side,using this find the eqn of the side which has points (2,1) and the unknown vertex


now,u can easily find the vertex as u hav the eqn on which it lies,and also its distance from a point


HOPE U R CLEAR  WITH THE SOLUTION
