The relationship between the radius of the near incircle of the 4ABC corner trisector is a comparison the product of the radii of the incircle mixtilinear tangent to the two tri-sector lines of angle 4ABC is equal to the ratio of the squared trisector lines. Then if there are several random triangles that have the same thing in common, namely one angle that is the same size, then the comparison between the values the incircle and incircle mixtilinear radii are the same.entriangleangle trisectorincirclemixtilinear incircleArticle
