If `I_1,I_2,I_3` are excentres of the triangle with vertices `(0, 0), (5, 12), (16, 12)` then the orthocentre of `Delta I_1 I_2 I_3` is

If I_(1), I_(2), I_(3) are excentres of the triangle with vertices (0, 0), (5, 12), (16, 12) then the orthocentre of DeltaI_(1)I_(2)I_(3) is

If I_(1), I_(2), I_(3) are excentres of the triangle with vertices (0, 0), (5, 12), (16, 12) then the orthocentre of DeltaI_(1)I_(2)I_(3) is

Find the area of the triangle whose vertices are.(i)(2,3),(-1,0),(2,-4)

If I_(1), I_(2), I_(3) are the centers of escribed circles of Delta ABC , show that the area of Delta I_(1) I_(2) I_(3) is (abc)/(2r)

I,I_(1),I_(2),I_(3) are the in centre and excentres of Delta ABC .If I(0,0),I_(1)(2,3),I_(2)(5,7) then the, distance between the orthocentres of Delta II_(1)I_(3) and Delta I_(1)I_(2)I_(3)" is
