Geometry was not taught with creativity and diverse thinking in the past, especially in primary school. Students were simply given theorems and axioms based on geometric figures and were not allowed to discover them for themselves, resulting in the deductiveness of geometry not being invented. Because geometry was presented as a body of information that had to be acquired by rote in most situations, this not only hindered students' ability to understand geometric concepts, but also created a negative attitude toward geometry among students and teachers.
