## 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 […]

## Learning from GRE Math Practice

I’m going to ask you a question whose answer seems painfully obvious. What is the purpose of doing practice GRE math questions? Take a minute to really consider that question in its entirety and explore the implications of your answer. If your answer was any of these, or something similar to these, then it’s too […]

## 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, […]

## Special Quadrilaterals on the GRE

Today, we’ll cover special quadrilaterals and the facts that you should know. These will allow you to answer questions quickly and understand the basic nature of these shapes.   1) A Typical Parallelogram All parallelograms have the BIG FOUR properties: 1. Opposite sides are parallel—AB // CD, AD // BC 2. Opposite angles are congruent—∠BAD […]

## Does Order Matter? Combinations vs. the Fundamental Counting Principle on the GRE

When trying to decide whether to use the combination formula, many students have trouble applying the “does order matter” test–deciding if outcomes differ. It’s easy to say order doesn’t matter when it in fact does, and vice versa. Once you get it, it’s really useful, but it can take a bit of thinking and re-thinking. […]
