This study investigates the mathematical reasoning abilities of middle school students in geometry during the implementation of distance learning. This research is qualitative with a case study design by analyzing students' mathematical reasoning abilities. The subjects in this study were 64 tenth grade senior high school students. The instrument in this study was a written test consisting of 5 questions. The questions were distributed to students by using google form due to the COVID-19 pandemic. Based on the research, it was obtained that the average mathematical reasoning ability of students was 64.5, which was categorized as a moderate category. Furthermore, the indicators of mathematical reasoning abilities that are mastered by students are (1) mathematical manipulation and (2) draw conclusions and compile evidence, while indicators of reasoning abilities that are less mastered by students are (1) draw conclusions from a statement, (2) assess argument validation, and (3) perform the generalization. These results indicate that the three indicators need to be improved in optimize students' mathematical reasoning abilities. © Published under licence by IOP Publishing Ltd.
