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: Excellent! 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.
