Geometry

Study this chapter to learn about:

■ Lines and angles

■ Triangles

■ Polygons

■ Circles

■ Solids and cylinders

■ The coordinate plane

A

bout 20 percent of the questions on the GRE will deal with geometry.

These questions will address your knowledge of geometric properties

and formulas and your ability to use these formulas to construct

algebraic relationships. When answering geometry questions, you

should generally follow these steps:

1. Draw the diagram and input all given information.


2. Infer all properties and relationships implied by the diagram.


3. Use these relationships to create algebraic relationships.


4. Solve for what the question is asking for.

Notice that the approach for geometry questions is in many ways similar to

the approach for word problems. In both cases, your ultimate goal is to use the

information given to construct algebraic relationships. The distinguishing element

of geometry questions is that you will use geometric principles instead of words to

create these algebraic relationships. This chapter focuses on these principles and

how they are tested on the exam.
