She then produced three-dimensional central cross-sections of all the six regular polytopes by purely Euclidean constructions and synthetic methods for the simple reason that she had never learned any analytic geometry.
Siya pagkatapos ay ginawa ng tatlong-sukat central cross-section ng lahat ng mga anim na regular na polytopes sa pamamagitan ng payak na Euclidean constructions gawa ng tao at pamamaraan para sa simpleng dahilan na siya ay hindi kailanman natutunan sa anumang analytic geometry.
