The triangle formed by joining the three excentres `I_1, I_2 and I_3`, of `Delta ABC` is called the excentral orexcentric triangle and in this case internal angle bisector of triangle `ABC` are the altitudes of triangles `I_1I_2I_3` Incentre `I` of `DeltaABC` is the ......... of the excentral `DeltaI_1I_2I_3`.
