In this lesson our instructor talks about proving segment relationship. She talks about five essential parts to a good proof. She also discusses reasons used in proof such as undefined, definitions, postulates, and previously proven theorems. She talks about congruence of segments and the theorem. She does some proof example for setting up proofs. Four complete extra example videos round up this lesson.

State what is to be proven
Use a system of deductive reasoning to complete the proof
Reasons in a proof include:
Previously proven theorems
