In this study, the effect of Cabri 2d software on drawings of height, perpendicular bisector in triangles and diagonal in polygons was explored. Case study method was used in the study. Diagnostic questions and computer assisted worksheets related to height, perpendicular bisector and diagonal concepts were developed as data collecting tools. Diagnostic questions were posed as pre- and post-implementations to total 25 students studying at 8(th) grade of an elementary school in Trabzon. Students' answers to questions were analyzed and presented in tables. As a result of the study, Cabri 2d software was found to positively contribute to students' better understanding of height, perpendicular bisector and diagonal concepts. Therefore, it's recommended to develop and use in the classes Cabri 2d assisted worksheets also for other subjects of geometry. (C) 2010 Elsevier Ltd. All rights reserved
