While in traditional mathematics teaching methods, it is possible to prove concepts while teaching geometry and to reach generalizations that require more complex definitions by using concept findings, while in today's geometry teaching, learning that activates the student's discovery process gains importance. In this context, the aim of this study is to examine ten different studies on the factors affecting students' learning of basic geometric concepts. In this study, document analysis method was used. The main purpose of document review is not to reach new information, but to reveal the current situation in light of different studies. During the data collection process of the research, ten different articles on the factors affecting learning basic geometric concepts in geometry teaching were examined by scanning Google Scholar. For the research, a keyword in the form of factors affecting geometry teaching was entered into the search engine at the scanning stage and ten different articles that were allowed to access full texts were examined. For the analysis of the data, 10 different studies made by the researchers were analyzed as a result of the document review. During the document analysis, descriptive analysis was carried out by looking at the sample, sample selection method, data analysis method, method and findings of the studies examined by the researcher, and the findings were presented in tables. As a result of the research, it was concluded that constructivist learning theories and methods are effective in teaching basic geometric concepts.
