Is this lecture we sketch an inductive proof that singular homology and simplicial homology are equivalent. The bulk of our time is spent proving the Five Lemma which states that in a commutative diagram between two exact sequences, if four of the maps between the sequences are isomorphisms, so is the fifth.
