The development of computer-assisted mathematics learning media based on the Geogebra guided discovery on the two-dimensional triangular learning material is intended for the 7th grade junior high school students. The aim of this research is to develop a learning media on the topic of two-dimensional triangle area assisted by the GeoGebra software that can improve the students’ learning outcomes. The learning media being developed is called SeGeo (triangle learning material with the help of GeoGebra software application) that includes instruction and exercise questions that are expected to be able to guide the students in finding/understanding the concept of the area of two-dimensional triangle with the approach of rectangle and square unit and students’ worksheets (SW). The development of this media was carried out by using the 4-D model. The media trial was carried out by involving class VII B students of Dau Junior High School 01 in.the Even Semester Academic Year of 2020/2021. The results of this research showed that the learning media being developed fulfilled the product quality requirements, namely valid, practical and effective, and able to improve students learning outcomes in the topic of area of a two-dimensional triangle.
