Students in this era need to grasp the concept of geometry instead of memorizing formulae. This is important for them to further their knowledge in geometry. The purpose of the research was to determine whether GeoGebra software influences year one students' performance in geometrical reflection. The research utilized an experimental research method. A total of 24 Year One students were randomly selected from an international school. The research used pre-test and post-test. The sample selected were taught and learnt by using GeoGebra software after the pre-test. Then, a post-test was given to them. A paired sample t-test was conducted and the results indicated a significant difference between pre-test and post-test. ANOVA was also conducted to test the influence of gender and ability level on student performance in geometrical reflection. The findings show a significant difference in the scores between genders. Similarly, the results also found statistically significant difference in scores among the three student ability groups. In conclusion, the study implies using GeoGebra enhances students' performance in geometrical studies. Implementing teaching and learning geometry using GeoGebra would help students to explore the concept more in detail and help them to build and develop their geometry knowledge.
