One of the mathematics subjects matters that is close to the student's life is geometry. Geometry is a field of mathematics that studies the points, lines, shapes, sizes, and dimensions of things. To understand geometry, the students need to have a clear visualization because geometry is not easy to learn. It takes the learning media so that learning geometry is easy to teach. The use of AR technology can answer one of the solutions to student difficulties in geometry matter. This study aims to develop a Mobile Augmented Reality application for Geometry in mathematics learning and determine its feasibility. This Research and Development used a model ADDIE. The procedure of this development research is done only until the Development stage. Data collection instruments consist of an expert validation sheet of material and media experts. The study showed that the validation results are to be obtained percentage scoring average of 98.025% with a very valid category. According to the results, the mobile augmented reality application for geometry was very feasible for use in learning of mathematics. © 2024 Author(s).
