Here's Looking at Euclid. Euclid 's fifth postulate of his "Elements" treatise is a distinctive axiom in Euclidean geometry . It states that if two lines are drawn which intersect a third in such a way that the sum of the inner angles (alpha and beta) on one side is less than two right angles (or pi radians), then the two lines inevitably must intersect each other on that side if extended far enough.
Euclid's fifth postulate cannot be proven as a theorem, but just by wearing this shirt you'll prove that you're a mathematical genius.
