Abstract
This paper discusses the proof of the concurrent from Gergonne point. The Gergonne point of a triangle is the point at which the three lines from vertices to the points of
tangency between the incircle and the sides of the triangle are concurrent. Concurrent
Gergonne point can be proved through several methods and using Ceva theorem. The concurrence of Gergonne point is also proved on excircle of triangle.
