Modeling the Interior Angles of a Triangle using Hawgent Dynamic Mathematics Software

The abstract nature of mathematics contributes to the low understanding of students' mathematical concepts. For this reason, it is recommended that educators use mathematical software which is allegedly able to reduce the abstraction. However, until now there has not been much exploration on the use of Hawgent dynamic mathematics software, especially on the problem of proving the properties of triangles. Therefore, this 4-D development study (Define, Design, Development, and Dissemination) obtained ICT-based media using Hawgent dynamic Mathematics software. The validation results from media experts and material experts are feasible and valid for several measurement components. The interview results revealed that the students found it helpful because the use of this media clarified the visualization of the triangle concept. To assist the teacher in explaining the material so that the teacher's overall observations strongly support the students' statements so that in the future they can use this media in other mathematics lessons. This research is only limited to development research, so it is hoped that this media can be used by further researchers and school teachers in mathematics learning.
