This geometry video tutorial provides a basic introduction into the hypotenuse leg theorem also known as the HL postulate. it's another triangle congruence theorem that helps you to prove that two right triangles are congruent to each other. This video focuses on geometry proofs using cpctc and two column proofs. It contains plenty of examples and practice problems.
