## Abstract

. In mathematics, reasoning ability refers to the capacity to arrive at a correct conclusion by using mathematical rules, properties, or logic. The purpose of this study was to examine students' reasoning abilities when solving problems involving polyhedron topic. The descriptive quantitative method was used in the research. The study enrolled 21 ninth-grade students from SMP Muhammadiyah Palopo. The following indicators of mathematical reasoning were analyzed: (1) Making mathematical statements orally, graphically, and in pictorial and written form; (2) Performing mathematical manipulation; (3) Compiling evidence, providing reasons or evidence for alternative solutions; (4) Concluding the statement; and (5) Checking the argument's validity. The data collection method used was to administer written tests to the research participants. The research instrument was a five-item test of reasoning ability on application questions. According to the mathematical reasoning ability test results on the polyhedron problem, three students (14.29%) possessed excellent mathematical reasoning abilities, while 11 students (52.38%) had good reasoning abilities. Five students' score was in the average level (23.81%), two participants (9.52%) had low-level mathematical reasoning abilities, and none (0%) of the students' score was at the meagre level
