The contradictions in the Bible are not deal breakers. The major contradictions come via the followers themselves who interpret via their religious culture, perception, or ego.
Contradictions in maths tend to be deliberate mind games of logic.
Spherical geometry informs us that all sphere triangles have greater than 180° and less than 540° in total, because no angle can be greater than 180°. Sphere triangles are sections of spheres, their sides are the arcs of spheres so the sides are curved following the form of the sphere.
Plane geometry is dealing with three points connected by straight lines in which case they are always 180°.
Both are right because they relate to differing forms.
These triangles differ sphere vs plain because they are applied to different forms. Next time you drive some place drive straight, don't take any of the bends and you will begin to see the difference of the sides of these two forms, otherwise you could make turns on straight roads and the shapes of these differing triangular forms will become apparent.
The problem with Bible teaching is that in the majority of cases the teacher has not got a clue what he or she is teaching and so ignorance flows on from age to age.
