Key ideas when proving mathematical ideas. Proof Points. Be Patient.. Finding proofs takes time. If you don’t see how to do it right away, don’t worry. Researchers sometimes work for weeks or even years to find a single proof. (Not very encouraging is it?). Soundness and Completeness. Two Notions of Logical Consequence. Validity: If the premises are true, then the conclusion must be true.. Provability: From the premises, the conclusion can be derived by the rules of inference of the system.. Objectives: To use detours in proofs and to apply the midpoint formula.. Procedure for Detour Proofs. . Determine which triangles must be congruent to reach the required conclusion. . Attempt to prove that these triangles are congruent. If you don’t have enough information to prove them congruent, take a DETOUR (follow steps 3 – 5). . trisectors. I CAN….
