If a right angled Delta ABCof maximum area is inscribed within a circle of radius R. then (Deltarepresents area of triangle ABC and r, r_(1), r_(2), r_(3)represent inradius and exradii, and s is the semi perimeter of then

Answer»

`DELTA = R^(2)`
`1/r_(1) + 1/r_(2) + 1/r_(3) = (SQRT 2 + 1)/R `
`r = (sqrt 2 - 1)R`
`s = (1 + SQRT2) R`
