The first solution for this example illustrates a formal twocolumn proof, introduced in Lesson 1.4. Emphasize that steps in a proof must not be skipped or omitted, and that a justification must be provided for each statement. Also emphasize that once a property is proved, it can be used in other proofs.The second solution models a visual/oral presentation of the proof. It does not include justification, although reasoning is found in the commentary.
