TRIANGULAR INEQUALITY A FORGOTTEN PROPERTY BY MATH TEACHERS
The use and applicability of the triangle inequality theorem and the Pythagorean theorem to construct and identify triangles in mathematics class was investigated. The qualitative research and descriptive scope yields valuable information regarding teacher training on the construction of triangles and their mastery of the subject. It was required to use concrete material for problem situations in the construction of the mathematical object. Five mathematics teachers from a private urban educational center in Sololá, Guatemala, were selected in a non-probabilistic, incidental and convenience manner because they have different university backgrounds and have more than four years of teaching experience.

Abstract:
The use and applicability of the triangle inequality theorem and the Pythagorean theorem to construct and identify triangles in mathematics class was investigated. The qualitative research and descriptive scope yields valuable information regarding teacher training on the construction of triangles and their mastery of the subject. It was required to use concrete material for problem situations in the construction of the mathematical object. Five mathematics teachers from a private urban educational center in Sololá, Guatemala, were selected in a non-probabilistic, incidental and convenience manner because they have different university backgrounds and have more than four years of teaching experience.
