文[1]介绍了以色列数学教师Л.Штейгарц对Morley定理作出的又一证明.该定理由英国数学家Frank Morley于1904年发现.文[1]首先证明了三个关于角平分线问题,并将其作为预备知识,然后应用它们证明该定理.其证法新颖.现摘译如下,供数学教师参考.Morley定理任意三角形角的相邻的三等分线的交点是等边三角形的顶点(图1). In [1], another proof of the Morley theorem by Israeli mathematical teacher Л.Штей гарц is presented by the British mathematician Frank Morley in 1904. [1] first proved three problems about the angle bisector and Using it as a priori knowledge, and then applying them to prove the theorem. The new proofs are now abstracted below for reference by math teachers.Morley’s Theorem The intersection of adjacent three bisectors of arbitrary triangle angles is the vertices of the equilateral triangle figure 1).
