Jul 18, 2023 · The development of non-Euclidean geometry challenged the idea that mathematics is based on absolute truths that are independent of human experience. Because the surface is curved, there are no straight lines in the traditional sense, but these distance minimizing curves known as geodesics will play the role of straight lines in these new geometries. Until the advent of non-Euclidean geometry, these axioms were considered to be obviously true in the physical world, so that all the theorems would be equally true. Used in mathematics an Architects use geometry to help them design buildings and structures. One of these models is better known as the Klein model, another one as the Poincaré disc model, the third as the Poincaré half plane model.
