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).
