CHAPTER 8 STUDY GUIDE!! Concepts You Need to Know: How to simplify a radical (pg 390) Pythagorean Theorem and it’s converse (8.1) How to determine if a triangle is right, acute, or obtuse (8.1) 45°-45°-90° triangles and 30°-60°-90° triangles (8.2) Sine, cosine, tangent (8.3 and 8.4) How and when to use the inverse of sine, cosine, and tangent (8.3 and 8.4) How to find perimeter Tips for Studying: Look at all of the homework problems from the sections – redo all of the problems you got wrong Look back at your notes and in the book Try some other practice problems in the back of the book (page 731) Go to the Textbook Website (follow the link from the Blackboard page) and do some of the practice problems and take the quizzes for each section. Correct the incorrect problems on your Trigonometry Quiz Pretend you’re allowed to have a “cheat sheet” on the test and make one (even though you won’t be able to use it on the test…it helps you study those concepts by writing it down).
