About a third of the math questions on the SAT deal with topics of basic geometry. The geometry tested on the SAT is less complicated than the geometry taught in high school. For the test, you will have to know about lines, angles, triangles, circles, polygons and other shapes, but you will not have to write out a proof or prove a geometric theorem. The SAT contains no trigonometry.

There are seven main categories of geometry tested on the SAT, as you can see in the table of contents on this page. In addition to covering these seven topics, we also provide a brief run-through of the basics of geometry so that you’re fresh on the concepts and terminology.
