Analysis on geometry skills of junior high school students on the concept congruence based on Van Hiele's geometric thinking level

Analysis of geometry skills using Van Hiele's geometric thinking level is an attempt to overcome students' difficulties in studying geometry especially the topic of similarity. The purpose of this study is to describe the geometry skills of junior high school students on the concept of similarity based on the level of thinking geometry of Van Hiele. The research method is qualitative descriptive with the subject of research is the students of SMP Negeri 2 Pontianak class IX as many as six people. The data collection instrument is a geometry skill test. The results of the analysis show that students at level one, two, and three from Van Hiele's geometric thinking level have all the skill such as visual, verbal, drawing, logic, and applied but different in characteristics for each level.
