Mathematics outcomes in South Africa are very low and many researchers and stakeholders have expressed concerns about the poor performance in mathematics at school level, especially in geometry (Luneta, 2015; Mthembu, 2007; Singh, 2006; Van Putten, Stols & Howie, 2010). Euclidean geometry forms part of the core curriculum of mathematics in the Further Education and Training (FET) band in South Africa; however, many learners seem to have the opinion that the study of geometry is irrelevant to their daily lives (Patkin & Levenberg, 2012).

欧几里得几何中相似三角形推理中符号表示的使用

南非的数学成绩非常低，许多研究人员和利益相关者对学校数学表现不佳表示担忧，尤其是几何学（Luneta，2015；Mthembu，2007；Singh，2006；Van Putten，Stols & Howie，2010 ）。欧几里得几何是南非继续教育和培训 (FET) 频段数学核心课程的一部分；然而，许多学习者似乎认为几何学习与他们的日常生活无关（Patkin & Levenberg，2012）。
