## 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 […]

## GRE Math: Solving Quantitative Comparisons

First off, here’s a tricky algebraic QC: 1) x > -3 If you find this puzzling, this article discusses an efficient method for handling such problems. Before we talk about that, a quick refresher on a few basic ideas dealing with equations and inequalities. Intro to Arithmetic Suppose you have an equation, P = Q. […]

## Coming Back to Math after Years Away

Suppose you have been away from math for a while, perhaps since Algebra Two and the SAT in high school. After these necessarily evils, you bid it a hasty farewell and gave it the bum’s rush from your entire life. Now, several years later, you have completed a Baccalaureate degree in something, and wish to […]

## Good! I Got it Wrong!

Children and more mature students typically differ in their response to getting a question incorrect. For younger children, and especially for self-absorbed teenagers, getting answers wrong can too easily be interpreted as some kind of negative personal message (e.g. “I’m dumb”, “there’s something wrong with me”, etc.) and it becomes a negative frustrating experience. Getting […]

## 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 […]
