SUMMARY

The discussion centers on the challenge of proving congruence using Euclidean axioms. It highlights that while one can derive congruence from the five axioms, the proofs often rely on unstated rules regarding the manipulation of triangles rather than strictly adhering to Euclid's original framework. The referenced document from the University of Georgia clarifies that these congruence rules are not directly derived from Euclid's axioms.

PREREQUISITES
  • Understanding of Euclidean geometry principles
  • Familiarity with congruence and triangle properties
  • Knowledge of axiomatic systems in mathematics
  • Basic proof techniques in geometry
NEXT STEPS
  • Study the five Euclidean axioms in detail
  • Explore the concept of congruence in triangle geometry
  • Research unstated rules in geometric proofs
  • Learn about real numbers' axioms and their applications in proofs
USEFUL FOR

Mathematicians, geometry educators, students studying Euclidean geometry, and anyone interested in the foundations of mathematical proofs.

TL;DR
Proving SAS, SSS, ASA and that in a triangle, the bigger the opposite angle, the bigger the side is and in an Isosceles triangle, the two angles are ‌equal.
So, given one, you can prove the others, but I don't know how to prove one with using the five axioms.

According to http://www.math.uga.edu/sites/default/files/inline-files/10.pdf, these rules are not proved using Euclid's axioms, but are proved using unstated rules about moving triangles around.
Thank you, could you introduce me another one but this time for real numbers' axioms and basic proofs?
