In geometry, the relationship between straight lines that meet at a certain angle is called the perpendicularity of the line. In other words, perpendicularity in geometry means the fact that a line is perpendicular to another line that passes through it. The perpendicularity of a line applies to all other similar geometric objects. Perpendicularity is […]

It is widely accepted that events can be categorized into two categories: compound and non-compound. There are many other types of events, but this one will hopefully give you a good understanding of the differences between these two categories. Compound events are those that are more or less the same thing over again, and they

The frequency distribution describes the distribution of a random number in the distribution of a specific sample, like a probability distribution. In a probability distribution, the expected value of a variable is calculated based on the sample and is expressed as a number with an expected value of zero or one and a probability. Frequency

The idea of multiplication is actually one of the simplest mathematical counting techniques you will likely encounter on the revised GRE General Test. The Multiplication principle can be described as follows: Each of the numbers in a sequence is equal to one multiplied by itself. For example, if there are m different possible pairs of

Triangles are geometric shapes that have three main parts, the side that faces out, two sides that face in, and the last one that face out (if you count the hypotenuse as a “side” of a square or a rectangular-shaped shape). Triangles are often used in architecture, in the shape of a star or an

What is the GRE Quantifying section? The GRE Quantifying section tests basic arithmetic, algebra, geometrical, and logic skills. Quantifying GRE subjects requires the knowledge of the different kinds of numbers, including decimals, percentages, exact figures, ratios, percentages, totals, and ratios. The test also tests properties, types of exponents, including exponents of great power, exponents of

Coordinate Geometry proofs utilize the use of mathematical formulas like the Slope Formula and the Midpoint Formula, as well as definitions, postulates and axioms. The proof can be quite lengthy and complex depending on the topic at hand. Show all of the work properly. Begin with a middle point and find that it lies on

Modifiers are commonly used on the GRE examination, and they’re not as common as you might think. However, they are a crucial part of every exam, and I’d like to share with you some tips on how to prepare for it. You see, GRE is a difficult exam, one where the “average” test taker will

The first part of the GRE examination is typically arranged in the form of a multiple choice quiz. The second part of the exam, which is called the Quantitative section, is designed to measure your ability to apply math to various situations. Both the math skills and reasoning skills are tested on this portion of

An angle measurement is the measurement of a surface or an object’s angle with respect to a reference point. It is usually taken on a line parallel to the ground. Usually, it is expressed in degrees. There are two types of angles. The first is the normal to a horizontal plane, and the other is
