Abstract
Geometry is a branch of mathematics that is important to learn. The way students think geometrically and communicate their thoughts both oral and written, certainly cannot be separated from the way they receive and process information. This study aims to analyze students^ geometric thinking abilty in Junior High School based on Van Hiele^s theory in terms of learning styles on the topic of line and angle. This research use qualitative method with a case study approach, which consisted of 40 junior high school students. The result showed that: 1) The level of Van Hiele^s geometric thinking ability of students who have visual learning styles most at level 0 (visualization). They have the same characteristics which is the ability to recognize angular shapes that were formed visually and more sensitive in observing elements of geometric shapes. 2) The level of Van Hiele^s geometric thinking ability of students who have auditory learning styles were in the range of pre-0 (pre-visualization) to level 1 (analysis). 3) The level of Van Hiele^s geometric thinking ability of students who have kinesthetic learning styles most at level 0 (visualization).
Keywords: Geometrical Thinking, Van Hiele^s Theory, Learning Style, Lines and Angles
