NON-EUCLIDEAN GEOMETRY
sites.math.washington.eduStrange Theorems Thus we can prove theorems in non-Euclidean geometry by proofs about the models. Some parallel line pairs have just one common perpendicular and grow far apart. Other parallels get close together in one direction. Angle sums of triangles are less than 180 degrees. There are no rectangles at all.

G odel’s Incompleteness Theorems
www.cs.nmsu.eduis provable from Peano’s postulates. This is known as G odel’s First Incompleteness Theorem. This theorem is quite remarkable in its own right because it shows that Peano’s well-known postulates, which by and large are considered as an axiomatic basis for elementary arithmetic, cannot prove all true statements about natural numbers.
