Abstract

Problems by junior high school students in learning mathematics is when solving math problems. Then conducted research aimed to find out the types and causes of errors made by students especially when completing mathematical questions on the inner circle and outer circle triangle to find alternative solutions and overcome the causes of the students' errors. The subjects of this study were students of class VIII5junior high school 5 Siak Hulu and totaling 36 people. This study uses a qualitative descriptive method. Data analysis techniques are descriptive analysis techniques. The data collection method used is the test method. Based on the results of the study, there were still many students who made mistakes in solving math problems in the subject of inner circle and outer circle of triangles. the types of errors are: misconceptions, principle errors, and operating errors in which the most common mistakes are the misconceptions of painting the inner circle and the outer circle of the triangle with the number of errors 60 and the percentage of 44.44%. 54 and a percentage of 40%, and a principle error of 21 and a percentage of 15.55%.
