Problem Statement

In the equilateral triangle ABCABC (AB=2AB = 2), cevians are drawn that do not intersect at one point. It turned out that the pairwise intersection points of these cevians lie on the inscribed circle of triangle ABCABC. Find the length of the cevian segment from the vertex of the triangle to the nearest point of intersection with the circle.
