- Write down formulas that you might need for the question.
- Ballpark if you’re stuck or running short on time.
These four steps, combined with the techniques you’ve learned in the rest of this book and the geometry
concepts this chapter will cover, will enable you to tackle any geometry question you might run across on
the SAT.
Before we dive in to the nitty-gritty, let’s try a problem using the approach.
25.In ΔABC (not shown), ABC = 60° and AC BC. If AB = x, then what is the area of
ΔABC, in terms of x ?A)B)
C)
D) x^2Here’s How to Crack It
Follow the geometry approach steps. Start by drawing the figure. If AC BC, then ΔABC is a right
triangle with the right angle at point C:
The next step is to label what you know. ABC = 60° can go right into the diagram. Because AB = x, you
can plug in for x; make x = 4. Label this information into the diagram:
