# Unit 3:

# GED® Geometry

# Shape Up

The good news: there's not a whole lot of Geometry on the GED® test. The bad news: the geometry that shows up most often- perimeter, area, and volume- tends to show up in some fairly complex ways. We've created this unit to build to the skill level you need to ace that test!
