The purpose of this study is to obtain an analytical description of students' critical thinking skills in solving trigonometry problems based on personality type. This research is a qualitative study with a descriptive approach. The results of this study are as follows: Student MHA with a guardian personality type met 1 critical thinking indicator on question number 1, which is focus, and met 6 critical thinking indicators on question number 2, namely focus, reason, inference, situation, clarity, and overview (FRISCO). Student MHA with a guardian personality type tended to be thorough in completing the given problems. Student AI with a rational personality type met 6 critical thinking indicators, namely focus, reason, inference, situation, clarity, and overview (FRISCO). Student AI with a rational personality type was good at analyzing and tended to ignore things deemed unnecessary or time-consuming. Student FA with an artisan personality type did not complete question number 1. Student FA with an artisan personality type met 3 critical thinking indicators, namely focus, reason, and inference on question number 2. Student FA with an artisan personality type tended to be slow in learning/understanding mathematical material, proven by the fact that student FA with an artisan personality type could not complete question number 1 and tended to rush in working on the problem. Student AL with an idealist personality type met 4 critical thinking indicators, namely focus, reason, inference, and situation. Student AL with an idealist personality type elaborated their answers in detail, both orally and in writing.
