Answer 5

Well, a inscribed circle in a triangle is defined by a the incenter, wich is the intersection between all the medians, now the radius is a whole other story.
Because no measure given by the medians will be evident to find the radius, because the circle will go off the perimeter of the triangle, and we don't want that.
What we have to do is take the incenter, or "E" in that case and fraw the distance from it to any side of the triangle, and by definition, a "distance" is a perpendicular segment from a point to a line.
so, with that, we can conclude that it's ED
