I searched online for different geometries. The website makes known the fact that the more common geometry taught in elementary school through high school is called Euclidean Geometry but there are also non-Euclidean Geometries.
Although I am not be there mathematically or may never be in terms of learning, can someone define in simple terms the following geometries?
What about geometry that deals with crop circles? What level of artistic geometry is this in all its form?
