Abstract
- The article provides information on attempt to prove Euclid's parallel postulate. Thales of Miletus attributed a false proof wherein he rests on the existence of a rectangle that is a quadrilateral with four angles. An English mathematician John Wallis failed to realized the assumption that two triangles can be similar but not congruent cannot be proved without the parallel postulate.
