<![CDATA[This study aims to analyze students' perceptions of polyhedral constructions in terms of the Van Hiele theory of geometric thinking levels. The method used was descriptive research with a qualitative approach involving 26 ninth-grade students of SMP YAPIS Manokwari. Data were collected through tests and interviews. The tests were used to identify students' geometric thinking levels, while the interviews were conducted to explore students' perceptions of polyhedral constructions and to verify the test results. The data were analyzed through data reduction, data display, and conclusion drawing. The findings revealed that the students were at the visualization and analysis levels. Students at the visualization level tended to understand three-dimensional figures based on their visual appearance and observable shapes, whereas students at the analysis level were able to identify component solids and recognize several geometric properties used in problem solving. However, students at both levels still experienced difficulties in understanding the relationships among the parts of composite solids comprehensively. In conclusion, students' perceptions of polyhedral constructions develop in accordance with their geometric thinking levels. Therefore, geometry instruction should be adjusted to students' stages of thinking in order to support the development of a deeper understanding of geometric concepts. Keywords: Geometry, Perception, Van Hiele Theory, Level of thinking]]>
