In this paper we report on a research aimed to identify and characterize secondary school students' reasoning and proof abilities when working with 3-dimensional geometric solids. We analyze students' answers to two problems asking them to prove certain properties of prisms. As results of this analysis, we get, on the one side, a characterization of students' answers in terms of Van Hiele levels of reasoning and, on the other side, a classification of these answers in different types of proofs. Results from this research give directions to grade and organize secondary school instruction on 3-dimensional geometry. [For complete proceedings, see ED489632.]
