@iteachalgebra: Geometry: Congruent Triangle Proof #tiktokencyclopediacontest #iteachalgebra #geometry #iteachmath #mathematics Note: this proof is done by getting all angles and all sides to have corresponding congruent angles! In later proofs, we settle into other congruence proofs that are much quicker, such as SSS, SAS, ASA, AAS, and HL!
