Activity 3: Practice & Review

Practice: Here is a helpful Web site by the Oswego City School District Regents Exam Prep Center. It shows the format of a two column proof and helpful information on the logic: http://regentsprep.org/Regents/mathb/1c/preprooftriangles.htm Scroll down the page and do the first three interactive proofs. Take note of the reasoning and study how the similarities and the logic works.
