Euclid's theorem proof

WebProof: Consider the set (1) K = { a x + b y x, y ∈ Z } Let k be the smallest positive element of K. Since k ∈ K, there are x, y ∈ Z so that (2) k = a x + b y Because Z is a Euclidean Domain, we can write (3) a = q k + r with 0 ≤ r < k Therefore, we can write r = a − q k = a − q ( a x + b y) = a ( 1 − q x) + b ( − q y) (4) ∈ K WebIf a straight line falling on two straight lines makes the alternate angles equal to one another, then the straight lines are parallel to one another. ("AIP", Euclid I.27) It is therefore distressing to discover that Euclid's proof of the Exterior Angle Theorem is deeply flawed!

WebThe proofs of the Kronecker–Weber theorem by Kronecker (1853) and Weber (1886) both had gaps. The first complete proof was given by Hilbert in 1896. In 1879, Alfred Kempe published a purported proof of the four color theorem, whose validity as a proof was accepted for eleven years before it was refuted by Percy Heawood. toyota service albany ca https://ltdesign-craft.com
