## Abstract

The purpose of this study is to describe the critical thinking of prospective mathematics teacher students in proving the geometry theorem. Critical thinking is one of the most important 21st-century skills needed by the world of work or industry, one of which is critical thinking. This type of research is a qualitative descriptive study with three research subjects mathematics education students of UIN Sunan Ampel Surabaya. The instrument of this study consisted of written tests and interviews in which the data were grouped and analyzed according to indicators of critical thinking. Based on the results of data analysis, it is found: (1) two subjects can write down and mention what is proven on the problem but some are correct and some are wrong, only one subject writes correctly and completely, (2) all subjects draw triangles correctly and mathematical symbols are written correctly, (3) all subjects can prove theorems correctly and systematically, and (4) two subjects re-check but the checks are incomplete and not systematic, while one subject does not verify the theorem. So it can be concluded that the critical thinking of prospective mathematics teacher students in this study in proving the geometry theorem is very good.
