This study aimed to compare the achievement in Geometry of the Grade 9 students of Abra State Institute of Sciences and Technology when grouped according to learning styles. A preference inventory was utilized to determine the learning style of the respondents while their achievement in Geometry was gauged using an achievement test. The quantitative-descriptive method of research was used in analysing and interpreting the data of the study. Majority of the respondents are visual learners. The kinesthetic learners performed best in all the three learning areas namely; Ratio and Proportion, Similar Triangles, and Pythagorean Theorem. The level of performance of the respondents in Geometry when grouped according to learning styles did not significantly differ. Whatever the learning style a student has, it does not affect his/her performance in school specifically in Geometry. Mathematics teachers may be encouraged to look and apply strategies that could enhance more the abilities of the learners which could also attract other learners with different learning styles to participate more actively the teaching-learning process.
