Abstract

This study focused on the use of dynamic geometry software to create a dynamic learning classroom for students of junior high school to reinvent relationship between external and internal angles of a triangle. By conducting explorative investigation aided with GeoGebra-based instructional media, students are able to explore and investigate this relationship so that they can formulate the relationship on their own words. In this way, students build their own understanding of the concepts and, thus the concepts are internalized well and long in the students’ cognitive
