The year 1842 found the first proof in print by a French mathematician: Lewin, M., On the Steiner-Lehmus theorem, Math. Mag., 47 (1974) 87–89. There are many other references for it, eg.,: Sauvé, L., The Steiner-Lehmus theorem, Crux Math., 2 (1976 V. Pambuccian, H. Struve, R. Struve: The Steiner-Lehmus theorem and triangles with congruent medians are isosceles hold in weak geometries. In: Beiträge zur Algebra und Geometrie, Band 57, 2016, Nr. 2, S. 483–497; V. Pambuccian, Negation-free and contradiction-free proof of the Steiner-Lehmus theorem.

Lehmus steiner theorem

converse theorem correctly: Theorem 1 (Steiner-Lehmus). If two internal angle bisectors of a triangle are equal, then the triangle is isosceles. According to available history, in 1840 a Berlin professor named C. L. Lehmus (1780-1863) asked his contemporary Swiss geometer Jacob Steiner for a proof of Theorem 1. The well known Steiner-Lehmus theorem states that if the internal angle bisec- tors of two angles of a triangle are equal, then the triangle is isosceles.

However, the proof does derIve a large part of Its development fram an 2011-10-01 We prove that (a) a generalization of the Steiner–Lehmus theorem due to A. Henderson holds in Bachmann’s standard ordered metric planes, (b) that a variant of Steiner–Lehmus holds in all metric planes, and (c) that the fact that a triangle with two congruent medians is isosceles holds in Hjelmslev planes without double incidences of characteristic ≠ 3.
