Chapter 16
Geometry
In this chapter, we'll cover all the geometry you need to know for the Mathematical Reasoning test—including lines and angles, triangles, rectangles, circles, volume, and graphing.
The good news is that the geometry on the GED® test covers only a fraction of what is covered in high school. Even if you never took geometry, you can learn everything you need to get the GED® geometry questions right just by reading this chapter and doing the exercises that follow.
Measuring Diagrams
One reason GED® geometry isn't too tough is that the diagrams are always roughly drawn to scale. As we showed you in our introduction to the Mathematical Reasoning test, this means that anytime there's a diagram, you always have a wonderful, concrete way to ballpark the problem. As we cover each of the geometry topics in this chapter, we'll show you how to measure the different types of diagrams.
