The greater the angle the greater side length theorem indicates that the order of the side lengths from least to greatest is; IJ < LK < IL < JL < IK

The steps used to find the order of the side lengths of the triangles from the least to greatest is presented as follows;

The measure of the angle ∠ILJ in triangle ΔIJL is; 180 - (55 + 81) = 44°

The measure of angle ∠ILK is; 180 - 44 = 136°

The measure of the angle ∠LIK is; 180 - (136 + 16) = 28°

The triangle greater angle greater side theorem indicates that we get;

m∠JIK is; 55 + 28 = 83°

Therefore in triangle ΔJIK, IJ < IK < JK

The angle side length theorem applied to triangle ΔJIL indicates;

IJ < JL < IL

The angle side length theorem applied to triangle ΔLIK indicates;

IL < LK < IK

Therefore; IJ < LK <

IJ < LK < IL < JL < IK
