TED-ED: How to prove a mathematical theory - Scott Kennedy

The video tutorial explains the significance of proofs in various fields, starting with Euclid's role in formalizing mathematics through axioms. It provides an example of proving triangle congruence using the Side-Side-Side Congruence Theorem. The tutorial highlights the importance of studying proofs, citing their applications in architecture, art, and technology, and mentions the potential financial rewards for solving complex mathematical problems.

What does Q.E.D. stand for and what does it signify at the end of a proof?

Discuss the relevance of proofs in various fields beyond mathematics.
