This one is not very difficult nikhil
Can you prove that for such a quadrilateral to have a circle inscribed it, the sum of opposite sides are equal?
(Sorry for the late reply on this one. I missed this question :(
1No problem sir...that's ok.
and yes, i used your clue.
so, AB=6, BC=5, CD = 3 and AD = 4.
By diagram, is the required radius (AD/2)=2?
