    Navigating Geometry for GRE: Essential Concepts and Test Strategies

    Geometry is a fundamental branch of mathematics that plays a significant role in the GRE. A solid understanding of geometry concepts and effective test strategies are essential for tackling geometry-related questions and achieving a competitive GRE score. In this article, we’ll guide you through the essential geometry concepts tested on the GRE and provide valuable…

  • GRE Geometry Formulas

    Perhaps you recall with more than a little dread your high school geometry class: fifteen-step proofs and the law of cosines were two things you were certain you’d never see again. Well, if you are taking the GRE, you were by no means mistaken—proofs and indeed all of trig are nowhere to be found on…

  • Diagonals of a Polygon in GRE Geometry

    Students love to skip over the basics, asking questions like: How many vertices does an octagon have? How many diagonals does an octagon have? What’s the difference between a regular octagon and, well, an octagon? And GRE geometry does delve into some complex polygon math. But before we get to that, I will begin with…

  • GRE Math: A Rectangle & Parallelogram with Equal Area

    Today, we’ll quickly look at how a rectangle and parallelogram can have the same area. In the diagram to the above, the parallelogram and rectangle share a vertex (D), one vertex of the rectangle (E) is on a side of the parallelogram, and one vertex of the parallelogram (C) is on a side of the…

  • Two Definitions of Exterior Angle in GRE Geometry

    This may come as a surprise, but there is more than one way to classify an exterior angle. You will want to have both of these definitions in mind when dealing with questions on the test since both instances are possible. Don’t worry! It won’t be too difficult to remember. Type I: At each vertex,…

  • How Many Geometry Questions are on the GRE?

    For the GRE Quant, you definitely need to know your geometry. But just how much should you be fretting about triangles, circles, and the like? Well don’t expect half of the questions in the math section to be geometry based. The real number is a little less than ten out of forty – though, depending…

  • GRE Geometry Diagram Assumptions

    What can you assume on GRE geometry diagrams, and what can’t you assume?  First, here are a couple of practice questions. 1) Quadrilateral ABCD is a rectangle. 2)   What you can’t assume on GRE geometry problems The biggie is: no diagram is drawn to scale.  That means — if nothing is specified about the…

  • GRE Coordinate Geometry Shortcut: No Graphs!

    For many, coordinate geometry is already a daunting concept. When a question dispenses with the graph all together, students can feel even more at a loss. If you fall into this group, do not despair. Here is a helpful guideline:   Do Not Always Draw the Graph This advice may seem counterintuitive. After all, the…

  • Will there be Parabolas on the GRE?

    Probably not. Meaning that parabolas can show up on the GRE, but probably won’t show up on the GRE you are taking. That is my initial take based on forums and students experiences. Still, parabolas, along with absolute value graphs, are included in the Practicing to Take the Revised GRE book. ETS obviously didn’t put…
