Abstract—Problem solving is one of four abilities which has
been emphasized in the 21st century. A problem type engaged to
explore students’ problem solving ability is non-routine
problem, particularly topic geometry. This research aims to
describe students’ problem-solving. It is a descriptive study
using qualitative approach. The result indicated that the high -
ability subject was quite able to understand the task and look
back the results. In addition, upon preparation and execution of
the plan, subject was able to do well. The medium-ability
subject was able to plan properly, despite quite capable of
understanding the problem, carry out the plan and looking
back her result. The low-ability subject figured out the problem
quite well, yet during plan preparation, plan execution, and
reviewed the work, subject performed adequately. It is
necessary for teacher to train and familiarize the students in
solving non-routine problem hence the students can experience
their own mathematical process.
