본 논문은 많은 교사들이 삼각형의 합동 조건에 대하여 불충분하거나 그릇된 이해를 하고 있다는 사실을 감지하고, 그 실태와 원인을 분석하고 대책을 모색하였다. 실태 조사 결과 대다수의 교사들은 삼각형의 합동조건은 세 가지 뿐이며, 두 변과 끼이지 않은 각이 주어졌을 때에는 반드시 삼각형이 하나로 결정되지 않는다는 잘못된 확신을 갖고 있었다. 분석 결과 그 원인은 주로 교과서가 제공하고 있었다. 연구 결과로서 교육과정의 기획과 교과서의 지필, 교사양성에 있어서 수정 보완 방안 일곱 가지를 제안하였다.

We recognized that most teachers are having insufficient understanding or misunderstanding about congruent conditions of triangles. So the purpose of this study was to analyze teachers's understanding about congruent conditions of triangles and to find the causes of teachers's misunderstanding. Most teachers have been misunderstanding that triangle determining- conditions are only 3 ways(SSS, SAS, ASA). And they have wrong confidence that 2 sides and a non included angle(ASS) is not always able to make one triangle. This study found that these teachers's misconception was from the textbook using now. As the result of this study, we suggested 7 improvement ways about planning of curriculum, writing of textbook and teacher training course.
