SUMMARY
The incenter \( I \) of triangle \( ABC \) is defined as the point where the angle bisectors of the triangle intersect. Given the side lengths \( BC = a \), \( AC = b \), and \( AB = c \), the distances from the incenter to the vertices are denoted as \( IA = x \), \( IB = y \), and \( IC = z \). The relationship \( ax^2 + by^2 + cz^2 = abc \) is established as a key property of the incenter in relation to the triangle's side lengths.
