The Incenter, Gergonne Point, and Tritangent Circles

The incircle is one of four tritangent circles which are tangent to all three sides of the triangle. The incenter (I) is the center of the circle. The Gergonne point is the point of concurrency of the lines drawn from a point of tangency between a side and the circle to the opposite vertex. Check and see if these two points are isogonal.
