Find Your Study Plan

The answer key shows where in this chapter to find explanations for the questions you missed.
Here’s how you should proceed based on your Diagnostic Test score.

6: Superb! You really know your plane geometry. Unless you have lots of time and just love to read
about plane geometry, you might consider skipping this chapter. You seem to know it all already.
Just to make absolutely sure, you could look over the plane geometry facts, formulas, and strategies
in the margins of this chapter. And if all you want is more plane geometry questions to try, go to the
Follow-Up Test at the end of this chapter.

4–5: You’re quite good at plane geometry. Some of these are especially difficult questions. If you’re
taking a “shortcut” or you’re on the Panic Plan, you don’t really have time to study this chapter, and
you don’t really need to. You might at least look over those pages that address the questions you
didn’t get right. You could also look over the plane geometry facts, formulas, and strategies in the
margins of this chapter. If you just want to try more plane geometry questions, go to the Follow-Up
Test at the end of the chapter.

0–3: You should read this chapter and do the Follow-Up Test at the end. You need to have a good
command of the material in this chapter before moving on to later chapters on solid geometry,
coordinate geometry, and trigonometry.
