Typically, there are very few geometry problems on the math test. The problems that are included tend to cover the basics: lines, angles, triangles, rectangles, squares, and circles. You may be asked to find the area or perimeter of a particular shape or the size of an angle. The arithmetic involved is pretty simple, so all you really need are a few definitions and formulas.
