Saccheri legendre theorem

WebThe Saccheri-Legendre Theorem is a Neutral Geometry theorem. There are (at least) two different ways to interpret what it means. One of these interpretations is that in Neutral Geometry there are some triangles whose angle sum is 180 and that there are some trian- gles whose angle sum is less than 180. A second interpretation is that given any ... WebAug 6, 2015 · Saccheri-Legendre theorem. Ask Question Asked 7 years, 7 months ago. Modified 7 years, 4 months ago.
